This Aluminum Flex Duct is intended to be used in heating, cooling, ventilation and waste gases transmission lines. Suitable for medium pressure application, it has an outer surface made of high quality aluminum foil and an inner surface made of metalized PET with inside high-tensile spring steel wire. Great emphasis has been invested in the design of this product to prevent it from kinking in sharp bends & turns, and to hold steady and at full diameter in all applications. All steel wire is applied between PET surfaces to prevent corrosion (oxidization).
