It is formed by molding flexible graphite tape or flexible graphite braided packing, metal materials can also be put in, they are often used together. It is mainly used for sealing of valves, pumps and expansion joints which are used in oil industry, chemical industry, thermoelectric station, nuclear, etc.
Die formed graphite packing ring is made of pure flexible graphite, or Graphite with nikle/SS316/Brass wire reinforced. Performance and Features
