3M 7000049613 Aluminum Foil Tape 48mm X 45m 3.25 Mil

Product Description

The 3M 7000049613 is an aluminum foil tape designed for sealing, patching, and vapor-barrier work in HVAC, insulation, and light industrial applications. It features a 2 mil aluminum foil backing bonded with 1.5 mil acrylic adhesive for a total thickness of 3.25 mil. The acrylic adhesive delivers strong resistance to elevated temperatures, UV exposure, and solvent contact. This tape is sold as a single roll measuring 48mm wide by 45 meters long and is handled by HVAC technicians, insulation contractors, and sheet metal mechanics during duct fabrication, repair, and insulation facing work.

This tape is suited for residential and commercial HVAC duct sealing, insulation jacketing repair, and interior finish applications where moisture, dust, flame spread, and chemical exposure are concerns. The foil face acts as an effective barrier against these elements. It carries UL 723 listing and US Coast Guard approval for interior finishes, making it appropriate for projects where code-compliant materials are required. The 40 lb polycoated natural kraft paper liner (Venture 1520CW) provides consistent unwind and clean release during application.

Key Features

• 2 mil aluminum foil backing provides a durable moisture, dust, and flame barrier
• 1.5 mil acrylic adhesive offers superior temperature, UV, and solvent resistance
• Total tape thickness of 3.25 mil for robust performance in demanding environments
• UL 723 listed and US Coast Guard approved for interior finish applications
• 40 lb polycoated natural kraft paper liner (Venture 1520CW) for clean, controlled unwind
• Roll format — 48mm wide by 45 meters long — suited for continuous sealing runs

Compatibility

Designed for use on HVAC duct systems, insulation facings, and sheet metal surfaces where a code-compliant aluminum foil tape is required for sealing and vapor-barrier applications.

Installation Notes

This tape is typically applied by licensed HVAC technicians or insulation contractors. Surfaces should be clean, dry, and free of dust or oil before application to ensure full adhesive contact. When used on duct systems, follow local mechanical codes and applicable SMACNA guidelines for sealing class requirements. Do not apply over wet or frosted surfaces, as adhesion will be compromised.
