ABSTRACT:
A coupling system for corrugated, flexible metal hoses includes fitting and washer assemblies. The fitting assembly comprises inner and outer fittings, the inner fitting being received on the hose and having a bore adapted to receive the washer assembly. The washer assembly includes an O-ring, a backer washer and an expandable washer. The O-ring forms a seal connection with the flexible metal hose and the fitting assembly. The expandable washer provides a stop against which the backer ring is pushed by the O-ring. The expandable washer is also clamped between the fitting assembly and a corrugation of the flexible hose to resist withdrawal of the latter. Modified embodiment hose coupling systems are also disclosed and include inner and outer gaskets, compression gaskets, termination plates mounting the outer fitting and different combinations of retainer rings, backer rings and gasket rings. An application of the coupling systems includes a fuel source, a fuel line, a manifold, the coupling system, a corrugated flexible hose and a gas-fired appliance.
