Interam gasket for wood stove catalytic combustors. Please measure the total of all four sides of your combustor to ensure you order the correct length. Always round up, this gasket may be trimmed with scissors or a blade to the exact length you need. Secure the gasket to the perimeter of your catalyst using masking tape. The masking tape will burn away after first use, and will not affect the performance of your stove or combustor.

Dimensions: 1/16" thick x 2" wide
