HVAC Premium 10'' Inch Flexible Aluminum Ducting Hose Insulated R-6.0 Air Duct Pipe for for Heavy Duty HVAC & Exhaust Ductwork Insulation - 25' Feet Long - in Accordance with UL 181

This aluminum flex duct is intended to be used in heating, cooling, ventilation, and waste gases transmission lines. Suitable for medium-pressure applications. 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). Produced in accordance with ISO 9001-2008 Quality Management System. Complies with industry standards of USA: ASTM D-882. European: EN 10270-1-SM. & EN 13180 standards. By means of the smooth surface, which the interior PET provides, this flex duct decreases the pressure loss and provides a more hygienic environment.
