4" 4-Layer Flex Ducting 25'

Our flex ducting is made with 4 layers of PVC and aluminum foil to bring you heavy-duty protection, without sacrificing versatility and flexibility. The inner aluminum foil layer is flame resistant and can withstand extreme temperatures ranging from -30 degrees to 140 degrees. The durable PVC outer layer protects the aluminum foil and is lightproof to regulate airflow temperature. Together these layers provide protection from leaks, punctures, and tears for long-lasting productivity. The flex ducting can be used for various ventilation applications including but not limited to HVACs, grow tents, greenhouses, and more. Ducting has a 4-inch diameter and comes in 10 and 25-foot options.
