Seal It Right is an easy to use sealant for installation and maintenance of direct vent appliances, such as gas burning systems and pellet stoves. May also be used to seal metal flues for wood and coal burning stoves. It flows to create a gasket, yet easily releases for cleaning or inspection. It withstands temperatures up to 800°F and does not release harsh pungent odors as with some other high temperature sealants. It becomes tough and flexible with air curing and further hardens with heat. Resists vibrations, cracking, fumes, gasses, moisture, and acids formed by gas combustion by-products.

Due to high solids content, it will not shrink or turn to brittle powder. Black latex cleans up with water within 15 minutes

Available in 10.3 ounce cartridge or 2.7 ounces tube
