It is a flexible braided packing which is made of an innovative expanded pure graphite yarn．The combination of other braided packing which is made of an innovative expanded pure graphite yarn．The combination of other braided packings installed with the excellentsealing capabilities of expanded pure graphite makes JM-P221 the most effective sealing component．It can be used to seal hot water，high temperature and pressure steam，leat transfer fluid，hydrogen gas，ammonia，organic solvents，hydrocarbons，cryogenic liquides，etc．，except fewer strong oxidizer．It is a unipue and universal sealing packing．In addintion，we can also supplyJM-P225(Flexible Graphite Braided packing Tube／Round Section)，Made of flexible graphite yarn through reinforcingand braiding，the section is rectangle (or round)，instead of normal square section．Applicable for underlay packing material of pumps，valves and vessels．Other performances are same as JM—P221．
