3M 7000124264 Duct Tape 6 in 12.1 Mil Blue Series 8979

Product Description

The 3M 7000124264 is a heavy-duty polyethylene foam duct tape engineered for demanding trade and industrial applications. Built on the Series 8979 platform, it measures 6 inches wide and 12.1 mil thick, with a rubber adhesive system delivering 36 pounds per inch of tensile strength. The tape is rated for continuous use up to 200 degrees F and is available in blue for easy identification on the job. Licensed contractors, HVAC technicians, and pipefitters reach for this tape where a strong, conformable, and heat-tolerant bond is required.

This tape is well-suited for residential and light commercial HVAC work, mechanical piping runs, and general construction tasks. Its polyethylene foam backing conforms to irregular surfaces, making it effective for sealing, bundling, and reinforcing. Each roll provides 54.8 meters of usable length, supporting full-day work on larger installations without mid-job changeovers. Applications include box closing, bundling, holding, identifying, joining, pipe bundling, protecting, reinforcing, sealing, splicing, and tabbing.

Key Features

• Polyethylene foam backing conforms to irregular and curved surfaces
• Rubber adhesive with 36 lb per inch tensile strength for high-hold performance
• Maximum operating temperature of 200 degrees F suitable for HVAC duct and pipe work
• Blue color aids visual identification and job-site organization
• Roll length of 54.8 meters reduces mid-job material changes
• Meets ASTM E-84 and UL 723 standards

Compatibility

Designed as a general-purpose duct and bundling tape for use across HVAC, plumbing, and mechanical trade applications where a conformable, high-strength polyethylene foam tape is required.

Installation Notes

Surface preparation is critical — clean, dry, and dust-free substrates achieve maximum adhesion. Apply firm, even pressure across the full tape width when bonding. For HVAC duct applications, verify local mechanical codes for approved taping methods and temperature ratings before installation. Store unused rolls in a cool, dry location away from direct sunlight to preserve adhesive performance.
