Dual wall co-extruded corrugated tubing (20) which includes an outer protective layer (22) fabricated from a relatively rigid plastic material, such as polypropylene or nylon, which provides crush strength, abrasion resistance, enhanced burst strength and enhanced thermal resistance for the dual wall co-extruded corrugated tubing (20) and an inner sealing layer (24) fabricated from a softer, more ductile, polymeric material, such as a thermoplastic elastomer (TPE), to provide a sealing surface for the dual wall co-extruded corrugated tubing (20).
