High Temperature Sealant/Gasket Material

A high temperature sealant (Exhaust sealant - for temperatures up to 2300°F) may be needed in addition to these mechanical fasteners to properly seal the connection from leaking exhaust gases. The best solution would be to minimize or eliminate the flue-pipe connections located inside the barn.

A source for this sealant is Cotronics Coproration.
