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.

I use a wood burning stove outdoors for boiling sap for maple syrup production. The sealant I used to seal the stovepipe liquefied, ran down the stovepipe and turned to ash upon cooling. My thermometer read around 500 degrees. Is there a sealant that can work in temperatures in excess of this?
