Overview
Restore a tight door seal and stop smoke, ash and air leaks around the door.
The braided fiberglass rope gasket seals the front door against the stove body so the stove draws air only where it is designed to. A flattened, frayed or loose gasket shows up as soot streaks on the glass edges, a door that closes without resistance, a smoky smell or an unsteady flame. Each kit is cut to the length your model needs and comes with high-temperature sealant to bond it into the door channel.
