ABSTRACT:
A refrigerant transporting hose having an inner tube including an inner and an outer rubber layer and an intermediate resin layer interposed between the inner and outer rubber layers; an outer tube formed of a rubber material located radially outwardly of the inner tube; and a reinforcing fiber layer interposed between the inner and outer tubes, such that the reinforcing fiber layer and the inner and outer tubes constitute an integral tubular body. The inner tube further includes a first adhesive layer for bonding the inner rubber layer and the intermediate resin layer to each other, and a second adhesive layer for bonding the intermediate resin layer and the outer rubber layer to each other. The first and second adhesive layers consist essentially of at least one elastomer, and at least one resin selected from the group consisting of phenolic resin and epoxy resin.
