Marine Hose
Specifications for fuel hoses used aboard small craft have
been standardized by the Marine Technical Committee of
the SAE (Society 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 vapors 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
compounds 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.

G682A TYPE A2 SOFTWALL MARINE FUEL FILL
G682A has the same features as G681A but with the helix wire left out. It is particularly useful in short lengths for joining filler necks to tanks where space is tight and wire reinforced hoses will not compress enough for easy installation.

G611A TYPE A1 FUEL FEED HOSE
G611A Type A1 Fuel Line is specially formulated and constructed
to meet the strict requirements set out by SAE
J1527 Type A1 Marine hose and is required for fuel feed
lines where the fuel is constantly sitting in the hose in an
enclosed engine compartment.
Note: Our G611A also meets European specifications for small
craft fire resistant fuel hose under reference ISO 7840/1994
Marine Fuel.

For these applications we provide a corrugated hose that requires less force to bend and offers a tighter bend radius. We stock G381C in the larger and more popular sizes. G381C meets SAE J2006 TypeR2 specifications for marine exhaust hose.
G388 SOFTWALL MARINE COOLANT & EXHAUST
G388 is for straight connections in engine cooling and wet exhaust applications and has the same features as G381 but without the helix wire. It is particularly useful where installation space is limited and a wire reinforced hose cannot be compressed enough to fit between the end connections. G388 meets SAE J2006 Type R1 specifications for marine exhaust hose.
| Tube: | Smooth, black, heat and anti-freeze resistant SBR rubber. |
| Reinforcement: | Plies of synthetic fabric. |
| Cover: | Black, heat and weather resistant SBR rubber with wrapped finish. |
