1/ Example of HCOF: for a -08, ½ hose OD, 20-1/2 inch assembly length, style A, the bulk
hose length = 20.50 - the HCOF = 20.50 -2.34 = 18.16. Bulk hose length required is
18.16 inches.
Hose assembly length. The hose assembly length is calculated as shown on figure 2.
Hose assembly elbow fitting drop height. Elbow fitting drop height B and C is calculated as shown on
