Abstract
A laminated fluid transfer hose construction having one or more intermediate metal barrier layers is provided, as well as, a hose assembly employing the laminated hose construction and coupling means. The inventive hose construction demonstrates improved barrier properties in the form of improved fluid permeation resistance, as well as improved durability. The hose construction may be convoluted yet still provide exceptional resistance to undesirable buckling, kinking and fatigue with no increase in fluid permeation due to necessary “thinning” of the walls to produce “flex.”
