These neoprene-coated polyester duct hoses are reinforced with a wire helix that provides strength and durability, preventing collapsing or kinking under pressure or vacuum. They are used to blow or exhaust air for dehumidification, enclosed space ventilation, portable air conditioners, preconditioned air, and general ventilation applications in foundries, municipalities, shipyards, and the aerospace and facility service industries. These flexible hoses are flame-retardant and self-extinguishing.

These silicone-coated fiberglass duct hoses have PTFE liners that resist weather and chemicals. These duct hoses are used in applications that need to remove chemical fumes. The hoses resist UV exposure and weather damage and will not kink. They have a smooth interior that maximizes airflow through the hose and minimizes friction. These hoses are highly compressible, which saves space when transporting them. They are not recommended for use with liquids or abrasive materials.
