1/ Example of HOCF: 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
figure 2. Drop height dimensions for B and C can be found in the applicable MIL-DTL-83798 slash
