2113na Hi-temp Flue Tape, Silver, 1-1/2 In. X 15 Ft.

3M Hi-Temp Flue Tape is a foil-backed silver tape designed to seal metal flue pipe joints on furnaces and stop hot air leaks at the seams of heating ducts. This high-temperature tape is heat-resistant up to 600°F, making it suitable for use in furnace and duct systems where standard tapes fail.

By sealing leaks where they start—at duct seams and flue joints—this tape helps prevent heated air from escaping and reduce energy waste. The 15-foot roll provides enough tape for multiple sealing jobs, and proper sealing can lead to noticeable heating cost savings and improved energy efficiency.
