Shurtape sf685-2spt Butyl Foil Tape 2in X 100ft

Product Description

The SHURTAPE sf685-2spt is a ShurMATIC butyl foil tape designed to seal HVAC duct systems in both indoor and outdoor environments. It features a waterproof aluminum foil backing with a butyl adhesive that stays supple and forms a permanent bond to the substrate. The tape is silver printed and comes with a liner for clean, controlled application. HVAC technicians and insulation contractors use it to create airtight, moisture-resistant seals on Class 1 flex duct, sheet metal ductwork, and duct wrap vapor barriers. The aluminum foil facing is paintable with any paint formulated for use on aluminum surfaces.

This tape is suited for residential and light commercial HVAC duct sealing applications. It is approved for indoor use on flex duct connections, sheet metal seams, and duct wrap vapor barriers. It is also approved for subgrade application on PVC-coated duct, making it a versatile option where both above-grade and below-grade installs are required. Each roll measures 2 inches wide by 100 feet long, providing sufficient coverage for single-system duct sealing jobs or targeted repair work.
