Nuclear Grade Duct Tape 8979N

3M 8979N is a red nuclear grade duct tape built for assembly, manufacturing, metalworking and warehouse environments. The polyethylene coated cloth backing and rubber adhesive suit continuous roll use in outdoor conditions. It is supplied new in a 48 mm by 54.8 m roll.

Adhesion and Temperature Limits

Adhesion to steel measures 57 oz per inch and the tape retains performance up to 200 degrees F. The 11.5 mil thickness provides mechanical strength for ducting and repair tasks. Beyond that temperature the adhesive can degrade and holding power drops.

Continuous Roll Format

The single continuous roll eliminates splices and simplifies dispensing on long seams or pipe wraps. No dispenser, cutter or extra adhesive is included in the package. Users needing pre-cut lengths or a hand-held dispenser must source those separately.

Questions about this item

Will the 48 mm width fit the ducting and conduit I already have in place?

The roll is 48 mm wide (1 7/8 in) so it matches standard duct sizes; verify your existing duct diameter before applying.

How can I confirm the 8979N tape is performing correctly once applied?

Press firmly to activate the rubber adhesive, then check that the bond holds at the rated 57 oz/in adhesion to steel and shows no edge lift up to 200 °F.

What comes in the box and what else might I need?

You receive one continuous roll of red nuclear-grade duct tape, 54.8 m long, 11.5 mil thick, polyethylene-coated cloth backing; no dispenser or extra adhesive is included.
