Hydraulic Hose Crimping Procedure

  1. Plug in, the metal clad provided
  2. Put on the selector switch
  3. Hold the hose to be crimped inside the die magazine
  4. Tighten the thrust collar by rotating clockwise till it grips the hose
  5. Put on the motor by pressing switch "ON" Set the depth of crimp with micrometer while using inch crimping switch
  6. "INCH" For production use switch "AUTO" Red Mushroom switch offers
  7. "EMERGENCY OFF" Electrical Circuit

Crimping or Swaging is the method of getting the fitting on to the ends of hydraulic hose. It is a simple compression method, using different sizes of dies and a compression collars. There are a many types of crimping machines for hydraulic hoses crimping in the market. The basic method is the same for each type of machine.

Tools and Materials required for the Hydraulic Hose Crimping

  • Fittings for Hydraulic hose
  • Hose lubricant
  • Chalk / marker
  • Safety goggles & Safety gloves
  • Ear protectors
  • Crimping machine
  • Crimping die and collar

Step 1: Measure the Hydraulic Hose Size

Measure the length of hydraulic hose that you need and cut it to size with a hydraulic hose cutter. This should give a clean edge hose, but if it hasn’t, use a file to clean the ends of hose. 

Step 2: Hydraulic Hose Fitting

Smear the end of the hose with lubricant and then push the hydraulic fitting onto the end of the hose. You must press/push the hydraulic hose as much as into the hose fitting as it can go in to. Draw a thick chalk/marker line around the hydraulic hose at the end of the hydraulic hose fitting. This is so that you can check the hose fitting after the hosed crimping process is completed.

Step 4: The die

The size of hose crimping die vary. Make sure that the crimping die in the machine is the correct size for the diameter of your hydraulic hose to be crimped.

Step 3: Adjust the Settings of hose crimping machine

The hose crimping machine has a number of micrometer settings. It changes from machine one to another machine. Select the correct setting for your hydraulic hose crimping machine.

Step 5: Place the Hose in Hose Crimping Machine

Push the end of the hydraulic hose up into the hose crimping machine and through the hose crimping die so that the hydraulic system hose fitting appears above the die of hose crimping machine. The top of the hydraulic hose, now concealed inside the hose fitting, should not be above the hose crimping die. On most of the hose crimping machines, you can now tighten the die slightly so that crimping die holds the hydraulic hose in place. 

Step 6: The Compression Ring for Hose Crimping

At this time use the compression ring. Put the compression ring or collar on top of the die for hose crimping.

Step 7: Safety Equipment

At this point in time put on your safety gear. You must wear safety goggles, ear protectors, and protective gloves for your safety.

Step 8: Crimping start

Turn on the hydraulic hose crimping machine: the cylinder head will move down slowly. As it pushes the collar of die, the collar will compresses the die. Not to touch the machine until the collar has reached firmly at the bottom of the die. The machine to then stop working. Almost each type of hose crimping machine has safety features inbuilt so that if the dies are displaced, the machine cuts out.

Step 9: Final Check

Check & verify the chalk mark which you made on the hydraulic hose. If it is no longer at the base of the hydraulic hose fitting, it means that the hydraulic hose or the fitting moved during the crimping. However tight it may appear, this is not a good and quality crimp. Otherwise, if the chalk mark is in place, you have successfully crimped the ends of the hydraulic hose with hydraulic fittings.
