<p>PROBLEM TO BE SOLVED: To provide a high performance low permeable hose capable of properly suppressing the permeation of a fluid such as a refrigerant and providing excellent vibration absorptivity and assembling workability by allowing excellent gas barrier capability and flexibility to co-exist with each other. SOLUTION: This low permeable hose comprises at least one layer of an elastic layer 1 and a reinforcement layer 2 stacked thereon from the inner layer side thereof. A gas barrier layer 3 formed of a resin material is spirally installed on the elastic layer 1. Desirably, an outer surface layer is installed on the outermost layer, and polyamide resin is used as the resin material. The reinforcement layer 2 is desirably be formed of a layer obtained by braiding or spirally winding a metal wire or a fiber material.</p> |
