The Builder’s Best Wire Helix Poly Vinyl Hose Standard Duct Tubing is engineered for dependable performance and durability, making it an ideal solution for bathroom fan ventilation needs. Constructed with a high-tensile steel wire helix, this duct features a 1″ pitch that is permanently heat-sealed between layers of tough polyvinyl chloride (PVC) film. This rugged build not only adds structural integrity but also ensures a long-lasting, reliable airflow channel. The white finish blends cleanly into most settings, and the flexible yet reinforced design offers a bend radius of just one diameter, making installation easy even in tight spaces.
Designed to handle air velocities of up to 2,000 feet per minute (FPM), this duct tubing supports a recommended maximum positive pressure of 1″ w.g. and a maximum negative pressure of 1/2″ w.g. across all diameters. It is suitable for continuous operating temperatures ranging from -20°F to 100°F, and can intermittently withstand up to 120°F. This temperature tolerance makes it reliable for various residential bathroom fan setups, even in environments with variable heat and humidity.
Please note: this product is not approved for dryer venting. Both the International Mechanical Code (IMC 504.6.1 & 504.8-3) and major appliance manufacturers require rigid or flexible metal ducts for dryer exhaust systems. Plastic or metal foil ducts, such as this polyvinyl hose, are not compliant with these safety standards.
