Shurtape pc857-3smt Silver Cloth Duct Tape 72mm X 55m

Product Description

The SHURTAPE pc857-3smt is a silver cloth duct tape rated UL 181B-FX, designed for sealing, seaming, and joining Class 1 Flex Duct systems in HVAC applications. The tape measures 72mm wide and covers 55 meters per roll, giving installers consistent coverage on standard flex duct connections. The UL 181B-FX listing means the adhesive and tensile strength meet the requirements set by Underwriters Laboratories, flex duct manufacturers, and applicable city and state building codes. It is intended for use wherever adhesion to stainless steel and polyethylene must satisfy strict performance standards.

This tape is used in residential and commercial HVAC installations for connecting and splicing air ducts and air connectors. It performs reliably when making transitions between flex duct sections and rigid duct components. HVAC technicians and sheet metal installers rely on this tape for professional, code-compliant duct sealing work where a UL-listed product is required by the authority having jurisdiction or the flex duct manufacturer.
