3M 7010302857 Aluminum Foil Tape 3.9 Inch UL181A-P

Product Description

The 3M 7010302857 is an aluminum foil tape designed for HVAC duct sealing applications requiring high-strength, high-temperature performance. The tape features a conformable aluminum foil backing coated with an acrylic pressure-sensitive adhesive. It meets UL181A-P, UL181B-FX, and ULC S102 specifications, making it code-compliant for use on listed duct systems. The roll measures 3.9 inches wide and 60.14 yards long. HVAC technicians and sheet metal contractors use this tape where printed, listed foil tape is required by inspection or code.

This tape is suited for residential and light commercial HVAC duct sealing. It performs across a wide range of temperatures and environmental conditions, making it appropriate for both conditioned and unconditioned space installations. Primary applications include rigid duct board sealing and flexible duct connections where a UL-listed foil tape is required by the Authority Having Jurisdiction. The conformable foil backing allows the tape to follow contours on rigid ductboard without lifting or bridging at edges.

Key Features

• UL181A-P, UL181B-FX, and ULC S102 listed for code-compliant duct sealing
• Acrylic pressure-sensitive adhesive for strong, durable bonds across temperature ranges
• Conformable aluminum foil backing follows rigid ductboard contours without lifting
• High-temperature performance suitable for supply and return duct applications
• 3.9 inch width provides efficient coverage on standard duct joints and seams

Compatibility

Designed for use on rigid duct board and flexible duct systems where UL181A-P or UL181B-FX listed foil tape is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following SMACNA guidelines and local mechanical codes. Clean and dry all substrate surfaces before applying the tape to ensure full adhesive contact. Avoid applying in temperatures outside the adhesive activation range and press firmly along the full length of each seam to eliminate voids. Do not use this tape as a substitute for mastic sealant where mastic is specifically required by the AHJ.
