Hose & Coupling Selection
Seven Easy Steps For Selecting The Proper HoseAn effective way to remember hose Selection criteria is to remember the to be conveyedP=PressureE=Ends or couplingsD=Delivery (volume and velocity)1. Hose size (Dash Numbers)The inside diameter of the hose must be ade-quate to keep pressure loss to a minimum andavoid damage to the hose due to heat genera-tion or excessive turbulence. See hose sizingNomographic Chart on page C63. To determine the replacement hose size , readthe layline printing on the side of the originalhose. If the original hose layline is painted overorworn off, the original hose must be cut andthe inside diameter measured for size . NOTE: Before cuttingan original hose assem-bly, measure the overall assembly length andfitting orientation. These measurements will berequired to build the replacement hydraulics industry has adopted a measur-ing system called Dash Numbers to indicatehose and Coupling size .
