Graphite is generally used in high temperature and high pressure environments and commonly finds applications in steam cycling or exhaust applications. These gaskets provide a higher performance seal in these conditions than non-asbestos jointing.

Graphite gasket material is almost pure carbon with the atomic structure arranged to form a soft, slippery material. To increase strength and reduce creep, graphite is often laminated with steel foil, wire mesh or stainless steel “tang” material.
