Corratherm 9631/P corrugated gasket

The Corratherm 9631/P corrugated gasket is a high-quality two-component gasket made from flexible graphite and stainless steel. Its core is made of a corrugated stainless steel profile ring with flexible expanded Statotherm graphite foil (purity ≥ 99.85 %) on both sides. Gaskets with an outer diameter up to 1,000 mm are produced in a single piece, while for larger dimensions, the metal base plate must be produced in multiple segments and welded together.
