High-Temperature Flue Tape 2113NA

3M Scotch 2113NA silver tape is a heat-resistant sealing product rated for temperatures up to 600 degrees Fahrenheit (315 degrees Celsius). It comes in a 15-foot roll that is one-and-a-half inches wide and applies directly from the roll onto clean, cooled surfaces. Designed for seasonal use on hot air ducts, it stops leaks in residential or light-commercial heating systems.

Replaces standard foil duct tape

Ordinary foil-backed tapes often degrade, become brittle, or lose adhesion when exposed to sustained flue temperatures. The 2113NA formulation withstands continuous heat up to 600 degrees Fahrenheit, so the upgrade is worth it whenever the duct surface regularly exceeds the limits of general-purpose tape. It is not intended for buyers who need a permanent structural repair or a tape that remains flexible after repeated thermal cycling beyond the rated ceiling.

Sustained heat performance

Under continuous operating temperatures the adhesive remains stable and the silver backing resists embrittlement for the duration of the heating season. The tape may lift previously damaged, cracked, or peeling coatings when removed, so surface condition affects long-term adhesion. Recommended practice is to clean the duct, allow it to cool, then apply the tape for seasonal service.

Questions about this item

What width and length does the 2113 tape come in so I can cover my duct joints?

The roll is 1-1/2 inches wide and 15 feet long, giving enough material for several standard duct connections.

How do I apply the 2113 tape correctly without it failing on the first heat cycle?

Clean the metal surface, let it cool completely, then unroll the tape directly onto the duct pressing firmly; skipping the cool-down step is the most common cause of early lift-off.

Will the 2113 tape need replacing after one heating season at 600 °F?

It is rated for seasonal use up to 600 °F (315 °C), so plan to inspect and likely replace it each year when used at the top temperature limit.
