Rutland Grapho-Glas gaskets are engineered to provide superior sealing protection and longevity when compared to other materials. The graphite-impregnated fiberglass resists creosote and soot adhesion that in turn provides better abrasion resistance. The braiding of the gasket and the staying power of our adhesive cement combine to make sure this gasket lasts much longer without failing or coming off. All of this makes Grapho-Glas the best choice for replacing your gasket. So good in fact that many stove manufacturers use Grapho-Glas as standard equipment on their stoves and fireplaces.
