    Silicone Sealants

    Sealants that are especially designed for high temperatures are needed for seating gaskets, sealing stove pipe, and setting roof flashing, as well as a number of other tasks associated with high temperatures stoves and their chimneys. Special formulations allow the sealants to maintain flexibility even under extreme conditions. Choose the sealant with correct temperature range for your application. Sealants are available in black, red, or clear so you can match brick, roofing materials, black stove pipe, or create a nearly invisible seal wherever it is needed.

    What sealant do I need to seal two metal stove exhaust pipes together? Is there a specific temperature? This will be leading to the chimney of a wood stove.

    Generally, you would not use a sealant as they don't make them able to stand up to those temperatures. The stove pipes should fit together and then you can drill them together.
