3M 1599B-SILVER_72X109.7 Duct Closure Tape 72mm Silver

Product Description

The 3M 1599B-SILVER_72X109.7 is a silver biaxially oriented polypropylene (BOPP) film duct closure tape designed for sealing and securing flexible air duct systems. The tape measures 72 millimeters wide by 109.7 meters long and carries a 3 mil total thickness. Its acrylic adhesive is formulated to perform across a wide temperature range, from -40 degrees F to 185 degrees F, making it suitable for installations in unconditioned spaces, crawlspaces, and cold-climate service work. HVAC technicians use this tape where a flexible, conformable closure solution is required on curved duct surfaces and irregular fittings.

This tape is rated for sealing flexible air duct and air connectors, securing flex duct to duct wrap facing, and making metal-to-metal connections and rubberized foam pipe insulation closures. It meets UL 181B-FX requirements, making it a listed closure system tape for use on Class 1 flexible air ducts and air connectors. The UV-resistant BOPP film backing holds up in attic and exterior-adjacent environments where direct or indirect sun exposure is a factor. Residential and light commercial HVAC service professionals are the primary installers of this product.
