Shurtape dc181-2blk Ul 181B-FX Film Tape Black

Product Description

The SHURTAPE dc181-2blk is a UL 181B-FX listed printed film tape engineered for use on Class 1 flexible air ductwork. It is designed for connecting, joining, sealing, and patching flex duct in residential and light commercial HVAC systems. The tape measures 48 mm wide and ships in 110 m rolls. Its pressure-sensitive adhesive delivers quick initial tack, and the film backing conforms readily to the irregular, ribbed surfaces common on flex duct. The UL 181B-FX listing is printed directly on the tape surface, making compliance verification straightforward during inspection.

This tape is used wherever Class 1 flex duct connections and seals are required. Typical applications include connecting flex duct to metal collars, boots, and fittings, as well as patching minor tears or sealing joints in flexible ductwork runs. The black color is matched to foil-backed flex duct, providing a clean, consistent appearance on finished installations. HVAC technicians and sheet metal contractors are the primary installers of this product.
