MARINE HOSE

A note about marine fuel hoses… Specifications for fuel hoses used aboard small craft have been standardized by the Marine Technical Committee of the SAE (So ciety of Automotive Engineers) under their specification J1527. Hoses can be broken down into four broad groups (A1, A2, B1, & B2) according to two requirements; fuel permeability and flame resistance. Fuel Permeability : Class 1 hoses have the greatest resistance to fuel vapours permeating through the hose itself. Therefore, in enclosed engine compartments where fuel is constantly in the hose, Class 1 hoses should always be used. Class 2 hoses exhibit less resistance to permeation, and so are intended for filler or vent hoses where fuel does not usually lie in the hose, or where there is no threat of fumes collecting in an enclosed area. Flame Resistance : Type A hoses have a flame resistant cover and will resist burning. Type B hoses have not been subjected to any flammability tests. Typically, fuel feed lines will be type A1, combining maximum resistance to permeation and to fire. Vent and filler neck hoses will be A2 or B2.

G681A… TYPE A2 HARDWALL MARINE FUEL FILL

USCG Type A2 Fuel Fill is designed using flame resistant com pounds to meet the fire resistance test required in SAE J1527 for USCG Type A marine fuel hoses. In addition, the wire helix allows the hose to be used around obstacles and in tight bends without kinking. Note : Our G681A also meets European specifications for small craft fire resistant fuel hose under reference ISO 7840/1994 Marine Fuel A2. Tube : Smooth, black, oil and heat resistant nitrile/PVC blend rubber. Reinforcement : Two plies of synthetic fabric and steel helix wire. Cover : Black, oil, heat and flame resistant neoprene rubber with wrapped finish. Temperature Range : -25°C (-13°F) to 80°C (176°F).
