ABSTRACT:
An object of the present invention is to provide ultra-low permeation hoses which have at the interior thereof a refrigerant barrier layer that consists in large part of a metal layer and is capable of conforming to hose deformation, which have an excellent resistance to refrigerant permeation (i.e., barrier properties to refrigerants), particularly an excellent CO2permeation resistance and an excellent heat resistance when CO2is used as the refrigerant. The object can be accomplished by an ultra-low permeation hose having at least a refrigerant barrier layer and a rubber layer and/or a resin layer; wherein the refrigerant barrier layer is a laminated film comprising a resin layer and, on the outside thereof, a metal layer, which the resin layer and the metal layer are bonded together by a polyamide-epoxy reactive adhesive.
