Multi-layer hose

A three-layer hose comprising:

• a laminated three-layer structure consisting of:
• an intermediate layer including a resin containing a polyester or a polyamide;
• an inner layer disposed on an inner periphery of the intermediate layer and consisting of epichlorohydrin rubber or hydrin rubber;
• and
• an outer layer disposed on an outer periphery of the intermediate layer and containing a rubber,
• wherein the rubber of the inner layer is in direct contact with the resin of the intermediate layer, with no intervening layer disposed therebetween,
• wherein the rubber of the inner layer is directly laminated to the resin of the intermediate layer by vulcanized adhesion, and
• wherein the laminated layer structure consisting of the intermediate layer, inner layer, and outer layer is formed using multi-layer extrusion such that each of the intermediate layer, the inner layer, and the outer layer has a continuous cylindrical cross-section.
