Graphite ring is widely used in many industry since it has such features of high temperature resistance, high pressure resistance, corrosion resistance. The graphite ring is always used for seal. The shape and size all can be customzied. If you need, please send us drawings or size. Resin impregnated graphite ring increase the strength and wear resistance. Surface profile and dipping can be added if you need.
