Ever wonder how a hose assembly is made. Here is a step by step guide to making of a standard hose assembly.
- First gather the materials and the tools that may be required, including the right hydraulic hose, hose fittings, hose lubricant, callipers, chalk, safety goggles, crimping machine, crimping die and collar.
- Next measure and mark the hose length you require ensuring that you have factored in the cut-off factor, and cut it to the right size with a hose saw. You should have a clean cut edge of the hose, otherwise use a file to clean the ends. Clean the hose ends properly in order to reduce hose contamination and hose failure due to the same. It is important to remove contaminants within the hose, using a hose brush, compressed air or projectile pellets.
- Select the right fittings, taking into account various factors including, working pressure, orientation, style, type and material for its compatibility with fluid and resistance to corrosion. Now, determine insertion depth of the fitting and mark a line around the insertion depth reading around the hose. Use lubrication on the hose ends if necessary, do not lubricate if you are using a spiral hose. Push the fitting into the hose ends, ensuring that the fitting end aligns with the insertion depth mark you had made earlier.
- We are now ready to prepare the hose for crimping. Ensure the capabilities of the crimping machine suits the hose size and adjust the settings to the correct crimp diameter for the hose assembly. Select the right crimper die set for the particular hose and fittings. Lubricate the die bowl with a lithium base grease if necessary. Place the hose end in the crimping machine, through the die so that the hose fitting now appears outside the die, ensuring the top of the hose (now inside the fitting) should not be above the die.
- Put on your goggles, ear protectors and strong protective gloves, do not compromise on your safety. Now, turn on the machine. As the cylinder head moves, it pushes the collar, which compresses the die till the collar is firmly at the bottom of the die. At this point the machine stops. All machines are equipped with a built in safety system to cut of f the machine if the die is displaced.
- Now check the mark you had made earlier on the hose. If the mark is in place, the crimping is successful and you can now check the crimp diameter on flat area on the crimped shell and verify it with the crimp diameter referenced on the specification chart. If it does not match, do not use the hose. Also, if the mark on the hose is not at the base of the fitting after crimping, it may mean the fitting or the hose moved during crimping and the hose should not be used.
- After a successful crimping, cap the assembly on both the ends, using plastic or heat shrunk caps.
