Source 1 1599S2 Duct Closure Tape 1.88in X 120yd Silver

Product Description

The SOURCE 1 1599S2 is a UL181B-FX listed flexible duct closure tape designed for sealing flexible duct systems in residential and commercial HVAC applications. The tape features a bi-axially oriented polypropylene (BOPP) film backing that resists UV degradation and conforms to curved and irregular duct surfaces. An acrylic adhesive backing is specifically formulated to maintain bond strength in cold weather conditions. At 1.88 inches wide and 120 yards per roll, this silver tape delivers consistent performance across a wide temperature range, making it a reliable choice for HVAC technicians who need a durable, code-compliant duct sealing solution.

This tape is suited for sealing and joining flexible duct connections in residential and light commercial HVAC systems. The flexible BOPP backing allows the tape to wrap around round duct collars, boot connections, and irregular fitting surfaces without lifting or creasing. The UL181B-FX listing confirms it meets industry standards for flexible air duct closure, which is required in many jurisdictions for duct sealing work under mechanical codes.
