3M 7000124263 Performance Plus Duct Tape 8979 Slate Blue

Product Description

The 3M 7000124263 is the Performance Plus Duct Tape 8979 in Slate Blue, a professional-grade pressure-sensitive tape engineered for both permanent and temporary fastening applications. The tape measures 72mm wide by 54.8m long with a 12.1 mil total thickness, providing substantial backing strength for demanding indoor and outdoor use. Its construction supports clean removal with little or no adhesive residue from most opaque surfaces for up to 6 months after initial application. HVAC techs, sheet metal contractors, and general trade professionals reach for this tape when a reliable, repositionable seal is needed without risking surface damage on removal.

This tape is suited for residential and commercial HVAC duct sealing, temporary weather barriers, bundling, and general construction or maintenance tasks. The UV-resistant backing holds up to one year of direct outdoor exposure, making it a practical choice for rooftop units, exterior mechanical rooms, and other applications where sunlight degradation is a concern. Its dual permanent and temporary performance profile makes it useful across a wide range of trade install and service scenarios.

Key Features

• Removable with little or no adhesive residue from most opaque surfaces up to 6 months after application
• UV-resistant backing rated for up to one year of outdoor exposure
• 12.1 mil total thickness for durable, tear-resistant performance
• 72mm x 54.8m roll size delivers extended coverage per roll
• Suitable for both permanent and temporary indoor and outdoor applications

Compatibility

Designed for general-purpose duct, construction, and maintenance applications across residential and commercial trade settings where a high-performance removable or permanent tape bond is required.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose debris for maximum adhesion. In HVAC applications, ensure ductwork surfaces meet local mechanical code requirements before taping joints or seams. No special tools are required, though a tape dispenser improves consistent roll-out and cut. For temporary applications, removal within the 6-month window minimizes the risk of residue transfer.
