1/ Class 2 fittings, styles K through V, are made from combination of aluminum and CRES.
2/ See figure 1 for depiction of styles.
3/ The HCOF is used in the following calculation to determine the hose length required to produce an assembly of a specific size, style and length: Assembly length - HCOF = Hose length. For example, the hose length required
to produce an 25.50 inch length assembly of size 10, style J is calculated as follows: 25.50 - 2.83 = 22.67.
Protective sleeve code: See table lll.
