Which tool used for crimping hydraulic hose?
Hand crimpers
Their portability and relative ease of use make them ideal for small-scale crimping jobs. Hand crimpers are most often used for piecework, low-volume manufacturing, and mobile assembly. Most welders and electricians will carry around a hand crimping device in their toolbag.
How does a hydraulic hose crimper work?
A hydraulic crimper works by using pressurised liquid to drive a piston down into a cylinder where it compresses a die against a cable, wire or hose being worked on. As this happens, the die forms a permanent bend at its point of contact.
What happens if you over crimp a hydraulic hose?
Over crimping can crush the hydraulic hose, blocking the fluid and weakening the hose. Under crimping can cause the end to blow off during operation. Crimping errors aren’t always visible to the naked eye, so be sure to check the crimp specs with a caliper before approving the finished product.
Hydraulic Crimping 101: Everything You Need To Know
Properly design the hydraulic hose. Hydraulic hoses are made up of three parts: tube, reinforcement and jacket. The hose is made of rubber and transports the liquid. Reinforcement is the less flexible braided wire wrapped around the pipe. The cover that surrounds both is the last line of defense from the elements and also adds strength to the hydraulic hose.
Most manufacturers provide hose identification information on the hose layline. Always verify that the hydraulic hose in question is the correct size (length and diameter) for the application.
Always follow the manufacturer’s recommendations for proper construction. Use the correct fittings designed for the hydraulic hose being used.
Before crimping the assembly, ensure the fitting is fully slid onto the hydraulic hose to prevent the end from being blown off during operation.
Be sure to use the correct crimp specifications when crimping the endform to the hose. Over crimping can pinch the hydraulic hose, blocking fluid and weakening the hose. Undercrimping can cause the end to blow off during service. Crimp failures are not always visible to the naked eye, so be sure to check crimp specifications with calipers before approving the finished product. Proper Hydraulic Hose Routing After the hose is properly assembled, it can be reattached to the implement. Routing is the positioning of the hydraulic hoses in relation to the equipment design. Incorrect routing can cause abrasion and weakening of the hose. The use of clamps and pivot points can prevent the hose from rubbing against the machine, thereby prolonging the life of the hydraulic hose. Using 45 degree or 90 degree fittings is common to route the hydraulic hose more efficiently. Use an appropriate bend radius Manufacturers provide information on maximum bend radius and should be followed to improve routing. The required bend radius of your hydraulic hose must be kept as large as possible to avoid flow restrictions and prevent kinking or flattening. Allow some slack in the length of the hydraulic hose to accommodate the movement caused by the fluid moving through the system. Watch out for extreme temperatures Extreme temperatures sometimes have a critical impact on the life of a hydraulic hose assembly. Outside temperatures and heat sources of the machine used or its surroundings can cause weak points in the hose construction. For this reason, proper routing techniques are essential. Hydraulic hoses should be kept away from the hot parts of the mechanism and other places where extreme heat is present. If this is not possible, use heat-resistant sleeves. Maintain proper operating pressure. The final step in preventing hydraulic hose failures is to avoid moving fluids at or above the hose working pressure (PSI). Constant use of hydraulic hoses at maximum pressure can cause blowouts and leaks. Some hydraulic systems are prone to dangerous pressure surges, if this is the case use a higher PSI hydraulic hose for normal flow. Pressure ratings should be listed on the hose layline.
All hydraulic hose assemblies will eventually fail, but delaying the process can save money and time. Following these steps can help ensure your hydraulic hose assemblies remain stable throughout their lifetime.

How many types of hydraulic hoses are there?
Hydraulic hoses generally fall into two categories: those that comply with SAE standards (the Society of Automotive Engineers) and EN standard hydraulic hoses – the European norm. SAE hydraulics hoses are generally regarded as the industry benchmark and the most widely used within the UK.
Hydraulic Crimping 101: Everything You Need To Know
Hydraulic hoses generally fall into two categories: those that meet SAE (Society of Automotive Engineers) standards and EN standard hydraulic hoses – the European standard. SAE hydraulic hoses are widely regarded as the industry benchmark and are the most commonly used in the UK. 16 different hose types fall within the SAE scope, and each must meet strict dimensions and performance specifications. Here are the main categories:
Braided hose :
Designed for general industrial applications, this high pressure hose is available in configurations with one, two or three braided steel wires. It is generally used with petroleum or water based fluids and operates at temperatures from -40°C to 100°C.
Multispiral Hose:
This type of hose is very flexible and due to its internal configuration it is particularly useful in heavy construction and high impulse applications. It is normally used to transfer mineral and hydraulic oils or water-oil emulsions, making it particularly useful for civil engineering, mining and quarrying, oil industry and agriculture, among others.
Low pressure hose:
This type of hose is braided with textile, which makes it very flexible, but not suitable for higher pressures. It is often used in lighter applications such as anti-static conveying, air, lubrication or return lines.
Stainless steel wire mesh hose:
These heavy-duty hoses, braided with single or double stainless steel wire, are used in aggressive applications such as chemical substance transfer. They are very durable and withstand extreme temperature and pressure conditions, even in a vacuum.
Thermoplastic hydraulic hose:
They consist of two layers of thermoplastic material separated by a middle reinforcement layer of wire or synthetic fibers. The fact that they can be operated at very low temperatures and are particularly resistant to abrasion makes them popular in hydraulically driven elevator systems and in lubrication lines where a small outside diameter is required.
How do I choose the right hydraulic hose?
Not all hydraulic hoses are created equal, so when looking for a new or replacement hydraulic hose it is important to consult with a specialist who can source or design the most suitable hose for your needs.
Variables affecting the type of hydraulic hose needed include:
The type of fluid flowing through the hose
The operating conditions to which the hose will be subjected (pressure/temperature)
Hose size (diameter and length)
Flexibility and durability of the hose
Ends and couplings (where the hose attaches)
Hybrid hose: isobaric constant working pressure
While the 100R1AT 1-wire hose – with varying working pressures ranging from 225 bar for ¼” diameter to 88 bar for 1″ – is widely used throughout the industry, Pirtek’s high quality hybrid hose offers the added benefit of constant working pressure across the range from ¼” to 1″ in diameter. The Pirtek range includes PFM25 (250 BAR constant working pressure), PFM35 (350 BAR), PFM35SX (350 BAR spiral) and PFM42SX (420 BAR spiral). This allows our mobile service units to work on a wide range of applications and ensures they can resolve over 95% of issues on their first visit.

What is a hose ferrule?
Hose ferrules are used with barbed hose fittings. They slide over the hose at the hose barb and crimp to create a positive seal. They help to provide fast, easy hookup for bulk hose pipe thread fittings.
Hydraulic Crimping 101: Everything You Need To Know
What is hose crimping?
“Crimping is the act of forming a metal sleeve or ferrule of the hose fitting with a surrounding series of die segments to compress the hose within the fitting,” he said.
Hydraulic Crimping 101: Everything You Need To Know
Upsetting Versus Crimping: What’s The Difference?
Danny Parks explained that an external die consists of a ferrule passed through a reducing die, usually split, to bring the ferrule OD to a predetermined size (for proper clutch retention), and then threading the tubing down into the stem splines to press. “Crimping is the forming of a metal sleeve or sleeve of the hose fitting with a surrounding series of tooling segments to compress the hose in the fitting,” he said.
The basic difference between the two processes is that the swaging process starts at the end closest to the hose and begins to reduce the ferrule moving towards the fitting, stopping at about ¾ of the height of the ferrule , creating a bell area that creates a pocket for the excess tubing to flow into. “In swaging, a machine pushes a fitting and ferrule through a fixed, split die bed to reduce the ferrule OD, thereby compressing the tubing into the stem serrations, while a crimping machine has any number of segmented dies wrapped around the ferrule or close sleeve and reduce to a predetermined OD. The crimping process simultaneously changes the shape of the entire circumference and length. It takes a lot more force (muscle) to crimp thick-walled ferrules all at once,” Parks said.
How to choose?
Parks noted that pressing is still the method of choice for the oil, petroleum and composites industries. “If you look at an oil rig, the length of hose called the rotary hose that is used at the drilling site is 3 to 4 inches in inside diameter. With a very thick wall, it is very heavy and typically withstands pressures of up to 5,000psi – something never seen in the industrial world. Very robust fittings are required and these fittings are connected by pressing.”
“Most industrial applications are now transitioning to crimping. One benefit is that crimping is automation friendly and can be integrated into any automated line with optional PLC controls and networking capabilities. Pressing has to be a practical process.”
He also pointed out that a crimping machine is expensive equipment, so many smaller companies currently using drop forging may not be ready to upgrade. “Kneading machines are robust systems that do not wear out. We continue to supply the crushable fittings to these companies. But for most larger, high-volume companies, investing in automated in-line crimpers is the growing process of choice,” he added.
Key areas to consider when choosing a process
For both processes, the key questions are: Which process best suits the application? What are the medium, working pressure, temperature and type of fitting for the application? Parks said most companies offer many types of permanently attached fittings and couplings for every type of industrial application.
“In the crimp/upset area alone, our original guide charts were about 300 pages. With so many different types of fittings and different types of ferrules and different hose IDs and all the assembly configurations you can think of, it was very confusing. We developed the King Crimp program and were able to bring together all these different ranges of crimp configurations for a wide variety of different fittings, all sharing the same basic barrel design so they all use the same ferrule and crimp specification. It is designed to provide different termination options by using the same ferrule or sleeve where the crimp specifications are etched directly onto the ferrule or sleeve.”
The best advice Parks can give anyone in this space is to turn to the expertise of a company that can pair it with the right technology. “For example, we don’t make crimping tools, but we do work with the equipment manufacturers and use their machine know-how and combine this with our specifications and our data to ensure that the final system is precisely tailored to users’ needs. Then we run training courses on their system and teach manufacturers how to use our King Crimp System.”
“It is always best to seek advice from an expert. Unfortunately, with all the information available on the internet, it’s all too easy to think that you’ve looked up all the answers online – and then still made the wrong decision. Asking for help is free and it’s always the right way. A wrong decision can cost a lot in the long run.”

What are crimping tools?
A crimping tool is the tool used to deform the material and create the connection. Crimping is commonly used in electrical work, to attach wires together or wire to other connectors.
Hydraulic Crimping 101: Everything You Need To Know
But how do you crimp and what tools do you need?
In this post, we’ll go over what crimping is and what tools you need to get the job done.
What is crimping and what is a crimping tool?
Crimping is a way of joining parts made of metal or other ductile material by deforming one or both parts to hold the other, and this deformation is known as a “crimp”. A crimping tool is the tool used to deform the material and make the connection.
Crimping is commonly used in electrical work to connect wires together or connect wires to other connectors. “Crimp connector” is the general name for the fittings that attach to the wire using this method, and usually have an insulated sleeve attached to a metal connector. The purpose of the crimping tool is to create a secure connection that is properly sealed from gas or moisture to prevent bottlenecks or faulty electrical connections.
Crimping is also used in manufacturing by mechanics and engineers who crimp a variety of different things.
What types of crimping tools are there?
There are many different types of crimping tools, each with different uses.
Here are the main types:
Crimping pliers for shoelaces
Designed for crimping ferrules/crimp sleeves, which are metal tubes attached to a color coded insulating collar.
They are commonly used in screw terminals to prevent multi-wire wires from splitting and can handle a range of common wire sizes.
Choose one with high leverage, like the Maun Bootlace Ferrule Crimper, to get a good crimp without tiring your hand. You can also choose the pliers version to crimp a wider range of sizes.
Precision crimping tool for thin cables
When working with thin wire, you don’t have much room for error, which is why traditional hand crimping tools can cause problems.
The solution to this is to use a ratcheting crimp tool like this, which helps control the crimp to remove human error from the process and ensure a good crimp every time, even on smaller cables.
Crimping tool for QM and IP68 connectors
These tools are designed to crimp QM connectors and IP68 connectors ideal for power control line connections as well as small transmission systems.
This tool can process QM connectors with wire size up to 24 AWG and IP68 connectors with wire size up to 28 AWG making it a versatile choice.
Crimping pliers for splice connectors
If you want to crimp splices, either gel filled or butt splice connectors, then you need a dedicated tool to do it, as opposed to a generic crimping tool.
This Scotchlok™ crimping tool accepts both Scotchlok™ 8A and 8B splice connectors and features a spring return for ease of use.
Crimping pliers for coaxial cables
A type of transmission line used to carry radio frequency signals such as broadband internet, coaxial cable has an inner conductor cable surrounded by a conductive shield, making crimping difficult.
Crimping tools for this type of cable are divided into different categories depending on the impedance of the coaxial cable (calculated in Ohm Ω). So make sure you buy one that fits your cable type.
Here are a few suggestions:
How to use a crimping tool
To start crimping you will need the following:
Cable
Interconnects
wire stripper
crimp tool
Here are the steps:
Strip the insulation off your wire to leave enough room for the crimp connector to slide onto the end. You can use wire strippers to do this. Twist the end of the wire to make the end tighter and allow for a better connection. Insert the connector into the crimping tool and gently hold it. Insert the wire into the crimp connector, and then apply firm pressure. If you’re using a ratchet crimping tool, it will automatically release as you crimp, so you probably don’t have to press as hard. You can test a bad crimp by pulling the connector and cable apart to see if it fails. It’s always better for a crimp to fail before you’ve installed it than after.
Can you crimp wires with pliers?
No, you can’t crimp with pliers as they don’t make the proper cold weld joint that a crimping tool creates. A bad crimp can allow air and moisture to get into the connection, which can lead to connection failure. Invest in a dedicated crimping tool instead.
Which is the best crimping tool?
The best crimping tools are made by Maun because:
They have been specially developed for various crimp connectors.
They are designed and manufactured in England to make secure connections.
They offer high leverage, so you need to apply less pressure.
Maun has a long history – they have been making tools since 1944.
Is crimping or soldering better?
Crimping typically provides a stronger and more reliable connection than soldering, as soldering can degrade over time and crimping is generally easier to perform. It’s much easier to crimp when you’re in a hard-to-reach place, like a B. when reaching cables in a ceiling or under floorboards.
How do you release a crimp?
It’s almost impossible to undo a crimp, and if you do, the second crimp is likely unreliable and can degrade over time. Your best option is to cut the wire and then lengthen it if it’s too short now.

How to Crimp a Hydraulic Hose
At Hydraquip, we offer the complete resource for all your hydraulic hose needs. As a Premier Platinum Eaton Aeroquip Partner, we take pride in ensuring that all assemblies are built to the highest standards. Each Hydraquip assembly is “ISO Clean” and comes with caps and plugs in place.
Crimping a hydraulic hose is a crucial aspect of any hose assembly. For multiple liquids or gases that are in motion for long periods of time, the crimp should be just right so the hose doesn’t damage the application.
When using an Eaton Aeroquip crimping machine, it’s important to know exactly how to use it to ensure consistent, high-quality hoses every time. Use this step-by-step guide when crimping your hydraulic hose.
Step 1: Measure and cut the tubing
Measure the length of tubing you need and use a tubing saw to cut it to the required size.
Step 2: Mark the insertion depth
Determine the insertion depth of the fitting using a hose insertion depth block. This mark indicates when the compression fitting is properly seated on the hose.
Step 3: Clean the hose
Use a foam projectile to remove any debris that may have accumulated from cutting the tubing. Cleaning the hose reduces contamination and hose assembly failure.
Step 4: Load the correct specifications
Choose the correct crimping diameter for each hose line.
Step 5: Select the cube
Crimper dies are designed specifically for specific hoses and fittings, so make sure the die is set to the correct specifications.
Step 6: Put the hose into the crimping machine.
Slide the end of the hose into the crimping machine and through the die so the hydraulic hose fitting appears over the die. The top of the tubing, now hidden in the fitting, should not be above the die.
Step 7: Crimp the hose
Your hydraulic hose can now start crimping. Turn on the machine. The cylinder head slowly moves down. When it squeezes the collar, the collar compresses the die. Do not touch the machine until the collar is firmly against the bottom of the die. The machine should then stop.
Step 8: Check the crimp diameter
Make sure the tubing is finished with the correct crimp diameter by checking the chalk mark you made on the tubing. If it is no longer at the base of the fitting, it means the hose or fitting moved during crimping. As tight as it may seem, this is not a good crimp. Otherwise, if the chalk mark is in place, you have successfully crimped the ends of the hydraulic hose.
Step 9: Cap the hose assembly
After you’ve cleaned the hose again, it’s a good idea to cap off the assembly at both ends. You can use plastic caps or shrink caps.

Hydraulic Hose Crimping
A well-crimped seal is essential for a functional and efficient hydraulic hose. But how is the work done?
A good, tight, even crimp secures the hose connection in place and allows the fluid to move freely without leaks. To properly crimp your hose, you need a crimping tool designed for use with a specific hose diameter. You should choose your crimpers based on the hose you will be using, not the other way around.
When assembling your hydraulic hose system, you should choose an appropriate hose based on a few factors: size, temperature, application, media, and pressure. While these factors are all important to the functionality of your hydraulic system, the size will determine which crimping tool you use to secure the fitting. Hose size is measured in diameter, and the size you choose can affect cost, pressure capacity, flow rate, and operational efficiency.
The tools
To crimp a hydraulic hose, you can use one of two methods: hand crimping or hydraulic crimping. Both are equally effective and can provide high quality crimps, but which one you use will depend on your performance needs (including crimp force and maximum crimp, the materials used, and sometimes even the brand of hose and/or equipment used).
hand crimper
As the name suggests, these tools are operated manually. Their portability and relative ease of use make them ideal for small crimping jobs. Hand crimping machines are most commonly used for piece work, small batch production and mobile assembly. Most welders and electricians carry a hand crimping tool in their tool bag. The tool has an opening tray and you can insert the right size crimp dies for the job, meaning they’re pretty versatile and easy to use.
The downside to these hand tools is that they are slightly less precise than their hydraulically powered counterparts. Hydraulic tools use what is called an “automatic crimp diameter” measured in microns, which ensures the tightest, most precise crimp on the hose. Hand crimping machines simply rely on the good judgment of the user and while they get the job done, ultra fine and accurate crimping can be better achieved with a hydraulically powered tool.
Hydraulic crimping tools
Hydraulic crimping tools are significantly more expensive than hand crimping tools, but they are also much more effective for high volume crimping. These tools are preferred for demanding industrial environments where crimping is a regular operation and heavy-duty machinery is required for maximum speed and precision.
These devices tend to be much larger, heavier, and more sophisticated than their handheld counterparts. It’s also faster and more powerful, capable of making multiple tight, accurate crimps at relative speeds. However, some hydraulic crimping tools have limited versatility as the crimp dies compatible with the machine strongly encourage the user to source parts from the same manufacturer.

Hydraulic Crimping 101: Everything You Need To Know
Hydraulic crimping is well known to those in the power or electrical industry, but crimping is actually used for a wide variety of applications. As a connection technology, it offers many advantages that cannot be achieved by soldering or field-assembled fittings.
In the context of electrical work, crimping is the process of making an electrical crimp – a type of solderless electrical connection. The same principle applies when crimping all types of wire, cable and tubing, such as B. when crimping hydraulic hoses. A crimping tool uses force to compress metal around a coupling, compressing and deforming the material between the two pieces of metal, creating an airtight and permanent seal.
We’ve compiled a list of frequently asked questions about hydraulic crimping that you might find useful. Read on to learn all about the crimping process.
What is a hydraulic crimper?
A hydraulic crimper is a tool used to join the ends of two cables, wires, or other similarly flexible materials such as hydraulic hoses to a mating hose end. This tool allows the user to make crimp connections through a hydraulic fluid mechanism to transmit power from the user to the tool.
These tools are also known as swagers, swaging presses, and hydraulic crimping machines. The key component in the system that creates the crimp itself is called the crimp head. Most commercially available crimping heads are single-acting hydraulic cylinders that open and close mechanical dies through various sliding surfaces.
How does a hydraulic crimper work?
A hydraulic crimper works by using pressurized fluid to drive a piston down into a cylinder where it presses a die against a cable, wire or hose being worked on. The matrix forms a permanent bend at its contact point. When the pressure is released, the die springs back up, leaving a permanently bent section of wire, hose end coupling, or cable clamp.
The hydraulically operated die opens and closes by pushing against a stationary surface on one side of the cylinder. When depressed, the hydraulic pressure forces the die into contact with another surface. When the desired compression or a certain size is reached, the hydraulic system releases its pressure and pushes the die back out. This allows the mold to be repeatedly opened and closed multiple times until enough material has been compressed to form a permanent seal between the surfaces. When crimping hydraulic hoses, it is recommended to crimp only once and to a size specified by the hose and hose end manufacturer. Also, leading hose and fitting manufacturers are always strongly discouraged from mixing and matching different brands of hydraulic hose and couplings, as hose manufacturing dimensions and fitting tolerances vary from manufacturer to manufacturer. Failure to comply could result in hose failure (hydraulic hose failure) under pressure, causing significant property damage, personal injury, or death.
The hydraulic crimping head can then be retracted, allowing you to remove the crimped hose without fear of damaging the newly created connection.
What is the benefit of crimping?
Crimping has several advantages. The main advantage is that crimp connections create an airtight seal between the connector and the cable, wire or hose, resulting in a durable and reliable connection that is protected from environmental conditions such as moisture, sand, dust and dirt.
Crimping pliers reduce labor and stress compared to alternative connection methods such as B. Field attachable connectors when used to crimp hydraulic hose ends.
Hydraulic crimping vs. mechanical crimping
The choice between a hydraulic and a mechanical crimping tool depends on preference, budget and application, among other things. Hydraulic crimping tools are either hand held or remote controlled compression tools that use the power of hydraulic fluid. On the other hand, mechanical crimping tools require brute force to operate. Most modern hydraulic hose crimpers are hydraulically operated with an electric motor driving the hydraulic pump and 12/24 or 240 volt solenoid valves controlling the movement of the crimping head.
Pros and cons of hydraulic crimping
Hydraulic crimping pliers offer many advantages. They can apply much more force than mechanical crimpers and feature advanced digital interfaces to increase productivity. Because these machines are hydraulically powered, they require little to no human input, eliminating human error and reducing human labor entirely. There are many different models that are perfect for whatever size workshop you have.
The great thing about hydraulic hose crimpers is that they save time and effort compared to mechanical crimpers. They work faster than human hands because they are under less stress. Unlike mechanical crimps, these machines also allow you to crimp larger diameter hoses without worrying about them breaking.
Unlike mechanical crimping tools that require manual force, you only need to press a button when the crimping tool touches the end of the hose. No more bending and stretching while trying to reach hard-to-reach places.
The main disadvantage of hydraulic crimping machines is that they require a larger initial investment. Although they save money in the long run, the initial cost is higher than that of a mechanical crimper.
Advantages and disadvantages of mechanical crimping
Mechanical crimping machines have fallen somewhat out of favor since the introduction of hydraulic crimping machines. However, they still retain some advantages.
Mechanical crimping machines are much less expensive, making it more effective for a company to buy them in bulk for staff use. In addition, they can be easier to repair if a part needs to be replaced or repaired.
Mechanical crimping machines are by no means bad, but they are inferior to hydraulic machines in their function. Manual versions are slower, less versatile, and require more physical labor than their hydraulic counterparts.
What is a hydraulic crimper used for?
Hydraulic crimping tools are mainly used for industrial applications such as plumbing, electrical wiring and automotive assembly. Crimping pliers are also used to make a permanent coupling that connects a hydraulic hose to a hose fitting. These types of crimping tools are ideal for large production lines where manual labor costs are high.
Automating this process has enabled companies to reduce staffing requirements and reduce downtime due to employee error. This allows companies to keep up with the increasing demand and remain competitive.
When repairing with hydraulic crimping tools, this joining method is quick to perform, can be performed off the shop floor, and extends the life of repairs.
Types of hydraulic crimpers
There are different types of hydraulic crimping tools depending on what you need. Every crimping tool has a different capacity, so it’s important to know what force and size you’ll be working with before investing in a machine.
Mini crimping tools
Mini crimping tools are among the smallest types you can find. Because of their relative price and relative power, these smaller machines are perfect for smaller projects that don’t require extremely high power. Mini crimping tools are compatible with a wide variety of bits and can reach over 10,000 psi with the right pump.
Mobile crimping tools
Mobile crimping tools close the gap between mini crimping units and larger industrial crimping units. The greatest benefit of portable crimping tools is their ability to combine portability with strength, perfect for on-the-go repairs. Most modern mobile crimping tools have a digital interface and have crimping forces in excess of 1,700 kN.
Workshop crimping tools
Shop standard crimping tools are the benchmark for many shops. These machines are robust and powerful, versatile and work consistently over many years. With crimping forces of over 2,000 kN, they are able to master any task you set them. With the capacity to crimp tubing up to 2 inches and in some cases even larger, you can count on these machines to provide years of efficient and consistent service.
Production grade crimping tools
Production level crimping tools are the cream of the crop. These heavy-duty units are as tough as they come, and you’ll find them in the workshops of many industry leaders across the country. Capable of handling up to 4 inch hoses in hydraulic shops with crimping forces in excess of 3,000kN, these machines are hardly anything these machines can’t do. When you’re ready to take your job to the next level, look no further than a production-grade crimping tool.
If you are unsure which type of hydraulic crimping tool is best for your needs, a reputable hydraulic crimping tool supplier can help you determine the one that best suits your needs.

What is the difference between crimping and pressing?
Crimping and swaging are both techniques used to create watertight and airtight seals around components such as hydraulic hoses. The result is very similar, but the process behind getting them to this point is different.
Crimping uses a powerful crimping machine to apply pressure in all directions to a hose coupling to create a tight seal. The pressure is applied evenly and once by a slowly closing matrix.
Pressing involves rapid continuous fasteners to form an elbow coupling into a smaller, sealed circular shape. The constant high-pressure closing molds the coupling around the hydraulic hose, embracing the circular shape.
Can you crimp without a crimping tool?
There is no right way to crimp connections without a crimping pliers or crimping tool. While it is possible to manually compress metal joints with pliers or other means, the results are not reliable or safe.
If using a crimping tool is not an option, it is safer to choose an alternative connection method than to perform a poor quality crimp. If you need to crimp connections frequently, it may be worth investing in a hydraulic crimping tool.
If you don’t want to invest in a larger, industrial crimping tool, there is a versatile selection of crimping tools for all price ranges. A range of smaller hand pump crimping tools are available for crimping hydraulic hoses that require a lower initial investment than workshop or production crimping machines.
