Graphite Packing Ring

Flexible Graphite Die (Graphite Ring, Graphite Gasket)is formed by molding flexible graphite tape or flexible graphite braided packing, and metal materials can also be put in together. It is mainly used for sealing or valves, pumps and expansion joints, which are used in oil industry, thermoelectric station, nuclear power station and other general industries. The property solves the problemof corrosion to the valve stem completely.
