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.
