3M Company 2113NA Hi-temp Silver Flue Tape 1.5 in X 15 Ft

Product Description

The 3M COMPANY 2113NA is a high-temperature silver flue tape rated to withstand temperatures up to 600 degrees F. It measures 1.5 inches wide by 15 feet long and is engineered to seal metal flue pipe joints on furnaces and stop air leaks from hot air ducts. The tape resists moisture and holds up under the thermal cycling that heating systems regularly produce. HVAC technicians and sheet metal installers reach for this tape when making field repairs or sealing ductwork connections that require a durable, heat-rated solution.

This tape is suited for residential and light commercial HVAC applications where flue pipe joints and hot air duct seams need a reliable seal. It performs in both indoor and outdoor environments, making it practical for exposed ductwork, utility room installs, and exterior flue runs. The silver facing integrates cleanly with metal pipe and duct surfaces common in gas furnace and air handler systems.

Key Features

• Rated to 600 degrees F for use on hot flue pipe and duct surfaces
• Resists moisture for indoor and outdoor installations
• Seals metal flue pipe joints on furnaces and gas heating equipment
• Stops air leaks from hot air ducts
• 1.5-inch width fits standard flue pipe joint overlap applications

Compatibility

Designed for use on metal flue pipe joints, hot air ducts, and duct seams in residential and commercial heating systems where high-temperature tape is required.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal installer. Power down the furnace or air handler and allow all surfaces to cool completely before applying tape. Clean and dry the mating surfaces thoroughly to ensure proper adhesion. Follow applicable mechanical codes, including IFGC guidelines, for approved sealing methods on venting and ductwork.
