Crimping a hydraulic hose is a crucial aspect of any hose assembly. With several fluids or gases in motion over extended periods of time, the crimp should be just right so that the hose does not damage the application.

When using an Eaton Aeroquip Crimp Machine, it is 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 hose

  • Measure the length of the hose that you need and cut it to the necessary size with a hose saw.

Step 2: Mark insertion depth

  • Determine insertion depth of the fitting by utilizing a hose insertion depth block. This mark will indicate when the crimp fitting is properly seated on the hose.

Step 3: Clean the hose

  • Use a foam projectile to get out all the debris that might have accumulated during the hose cutting. Cleaning the hose will reduce contamination and hose assembly failure.

Step 4: Load in the correct specifications

  • Choose the correct crimp diameter for each hose assembly.

Step 5: Select the die

  • Crimper dies are specifically designed for certain hoses and fittings, so make sure to verify the die is set to the correct specifications.

Step 6: Place the hose in the crimping machine.

  • Push the end of the hose into the crimping machine and through the die so that the hydraulic hose fitting appears above the die. The top of the hose, now concealed inside the fitting, should not be above the die.

Step 7: Crimp the hose

  • Your hydraulic hose is now ready to begin crimping. Turn on the machine. The cylinder head will slowly move down. As it pushes the collar, the collar compresses the die. Do not touch the machine until the collar is firmly at the bottom of the die. The machine should then stop.

Step 8: Verify the crimp diameter

  • Make sure the hose is finished to the correct crimp diameter by checking the chalk mark which you made on the hose. If it is no longer at the base of the fitting, it means the hose or the fitting moved during the crimping. However tight 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 hose assembly

  • After you clean the hose again, it is a good idea to cap the assembly on both ends. You can use plastic caps or heat shrink caps.
