1/ Class 2 fittings, styles K through V, are made from combination of aluminum and CRES.

2/ For depiction of styles see figure 1.

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 30.00 inch length assembly of size 20, style F is calculated as follows:

30.00 - 4.68 = 25.32.

Protective sleeve code: See table lll.

TABLE III. Protective sleeve code.

Code	Type
A	SAE AS1072 sleeve, fire protection, silicone covered, temperature ranging from -65°F to 500°F, secured with CRES bands as required. 1/

1/ To prevent wicking of fluids, the cut end of the fire protective sleeve (code A) shall be coated with Room

Temperature Vulcanized (RTV) silicone rubber prior to installation. After installation, cracks and voids in the fire protective sleeve shall be coated with RTV rubber to prevent exposure of asbestos or fiberglass.
