Semi-Metallic Gaskets

Chesterton’s semi-metallic gaskets are engineered for demanding industrial applications where robust sealing matters. Constructed with a metal core (often stainless steel) and soft sealing layers like graphite or PTFE, they handle extreme temperatures, high pressures, and thermal cycling while maintaining excellent recovery and leak resistance.

These gaskets are ideal for use in heat exchangers, pipe flanges, vessels, reactors, and more—delivering reliable sealing performance in critical sectors such as petrochemical, power generation, and refining.
