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 -2.12 = 18.38. Bulk hose length required is
18.38 inches.
Hose assembly length. The 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
sheet as specified in table I herein.
