3M 7000049207 Performance Plus Duct Tape 8979 Slate Blue

Product Description

The 3M 7000049207 is a heavy-duty duct tape designed for both permanent and temporary fastening, sealing, and bundling applications in residential, commercial, and industrial settings. Sold as tape 8979 in slate blue, this roll measures 96mm wide by 54.8 meters long with a 12.1 mil total thickness. A licensed HVAC tech, insulation contractor, or general tradesperson will reach for this tape when a job demands strong holding power alongside the option for clean removal. The pressure-sensitive adhesive releases from most opaque surfaces with little or no residue for up to 6 months after application, reducing rework time on temporary installs.

Tape 8979 suits a wide range of indoor and outdoor applications including duct wrap, vapor barrier seaming, insulation facing repairs, and temporary masking on job sites. The UV-resistant backing holds up to one year of direct outdoor exposure, making it suitable for exterior mechanical systems, rooftop HVAC equipment staging, and any short-term weatherization work. Its dual-use design means a single roll can handle both permanent seals and temporary bonds without switching products mid-job.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose debris for maximum adhesion. On HVAC duct systems, verify that the tape meets any applicable local mechanical code requirements for the specific application before use. When used for temporary masking or staging, remove the tape within the 6-month window to minimize adhesive transfer. No special tools are required beyond a tape dispenser or utility knife for clean cuts.
