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.
