Chesterton 199 High Temp Gasket

Chesterton 199 High Temp Gasket
Foil-Inserted Inhibited Graphite


​​​​​​​​​​​​​​​​​​​​​​​​​​​​Designed for high temp applications, Chesterton 199 is a high purity, chemically inert graphite sheet with a 316 stainless steel foil insert for extreme stability. 199 contains a corrosion inhibitor to prevent galvanic attack of flange faces. Its excellent thermal stability, chemical resistance and negligible creep characteristics make it a truly universal sheet gasket.
