3M 7100043929 Aluminum Foil Tape 2.83 in X 60.14 Yd UL181A-P

Product Description

The 3M 7100043929 is a UL-listed aluminum foil tape engineered for high-temperature duct sealing applications in HVAC systems. It features a conformable aluminum foil backing coated with an acrylic pressure-sensitive adhesive, delivering strong, durable bonds on rigid duct board, flexible duct, and sheet metal surfaces. The tape carries UL181A-P, UL181B-FX, and ULC S102 listings, making it a code-compliant choice for sealing air distribution systems. It is used by licensed HVAC technicians and sheet metal contractors on both new installations and service work where a listed, pressure-sensitive foil tape is required.

This tape is suited for residential and light commercial HVAC duct systems. It performs across a wide range of temperatures and environmental conditions, including high-heat environments common to supply plenum and duct board assemblies. The conformable foil construction allows it to seal irregular surfaces and joints on rigid fiberglass duct board as well as flexible duct connections. Where a UL181A-P or UL181B-FX listed tape is specified by code or job requirement, this tape meets that standard directly.

Key Features

• UL181A-P, UL181B-FX, and ULC S102 listed for compliant duct sealing installations
• Acrylic pressure-sensitive adhesive bonds to rigid duct board, flexible duct, and sheet metal
• Conformable aluminum foil backing seats against irregular duct surfaces and joints
• Rated for high-temperature performance in supply-side HVAC duct applications
• 2.83-inch width covers standard duct board seams and lap joints in a single pass

Compatibility

Designed for use on rigid fiberglass duct board, flexible duct, and sheet metal duct systems where UL181A-P or UL181B-FX listed tape is required per local mechanical codes.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal mechanics. Shut down the air handling system before applying tape to pressurized duct sections. Surfaces must be clean, dry, and free of dust or oil for the acrylic adhesive to achieve full bond strength. Installations should conform to SMACNA duct construction standards and applicable local mechanical codes governing listed duct tape applications.
