Refrigerant transporting hose

A refrigerant transporting hose comprising:

• an inner tube for transporting a refrigerant, said inner tube including an inner and an outer rubber layer and an intermediate resin layer interposed between said inner and outer rubber layers, said intermediate resin layer resisting permeation of said refrigerant therethrough, said inner rubber layer having a thickness of 0.05 to 1 mm, said intermediate resin layer having a thickness of 0.05 to 0.5 mm, said outer rubber layer having a thickness of 1 to 3 mm;
• an outer tube of a rubber material radially outwardly of said inner tube, said outer tube having a thickness of 1 to 2.5 mm;
• and
• a reinforcing fiber layer interposed between said inner tube and said outer tube, said reinforcing fiber layer being adhesively bonded to the inner and outer tubes to constitute an integral tubular body,
• said inner tube further including
• a first adhesive layer for bonding said inner rubber layer and said intermediate resin layer to each other, and a second adhesive layer for bonding said intermediate resin layer and said outer rubber layer to each other,
• said first and second adhesive layers consisting essentially of at least one elastomer, and at least one resin selected from the group consisting of phenolic resin and epoxy resin, a ratio of said at least one resin to said at least one elastomer falling within a range of 95% by weight/5% by weight to 60% by weight/40% by weight.
