3M High Temperature Flue Tape stops hot air leaks right where they start — the seams of heating ducts and flues. Heat resistant up to 600°F, it holds up to the sustained high temperatures found in duct and flue applications without breaking down or losing adhesion. Sealing these seams helps reduce heating costs by keeping conditioned air where it belongs instead of escaping through gaps and joints. The 1.5-inch by 15-foot roll is sized for spot repairs and full seam runs alike, and the tape is made in the USA. Intended for indoor use on ducts and flues — not recommended for use on wood-burning stoves.
