Seals & Sealing Systems

Gaskets & Sheet

This unique new gasket material is designed for use in high temperature sealing applications, is able to withstand continuous and thermal cycling temperature up to 1,832ºF (1,000ºC). Its proprietary formulation is oxidation resistant, provides electrical insulation and has the ability to resist absorption of water and other liquids.
