Selecting Proper Hydraulic Hose for Your Appliion

Size The hose I.D. must be sized accurately to obtain the proper flow velocity. A flow that’s too slow results in sluggish system performance and a flow that’s too high causes excessive pressure drops, system damage, and leaks. Use the Flow Capacity Nomogram to determine the proper hose I.D. for your appliion’s flow rate requirements.
