The Rutland door and window grapho glass gasket kit is all you need to replace worn stove and fireplace insert gaskets each year. Our kit contains a tube of cement, making it convenient to keep your fireplace or stove airtight and free of creosote and soot. Graphite impregnated, braided fiberglass is engineered to provide superior sealing and resist fraying and abrasion. 7 feet of gasketing is just the right amount for most applications.
