- Choose a hose that has suitable working pressure for the machine application. Read the layline on the hose and duplicate as closely as possible to the hose type and pressure rating. If the rating can't be read do to UV fading, or age wear, find the repair manual and double check. It will be worth your time now, to save on premature repairs.
- Match the fluid viscosity to the operating temperature. You will achieve maximum component life if you duplicate the original grade of fluid viscosity to the operating temperature range of the hydraulic system.
Confirm you are using hydraulic hose compatible to the fluid being pushed through the hose. Not all hose is meant for all applications. When in doubt, check with your supplier to confirm the hose being ordered will work with the fluid in the application.
- Select the hose coating to support the environment where the hydraulic hose will be exposed. If there is potential for damage from pinching or crushing, consider adding protective sleeving over the hose. It will prolong the life of the hose and keep you from premature repairs.
Examine the current inner/outer diameter of the hose you are replacing. Make sure and replace with comparable size. This will protect against unwanted friction and flow restriction. Friction creates heat, heat creates back pressure increase and if the flow rate is reduced, cutting down on reliability and productivity in addition to potentially damaging other system components. -
