High temperature proof graphite seal is used as suitable sealing component for fire tube, exhaust stack piping flanges of compressor engine, compression valve, pump and so on. Seal or gasket of graphite is produced from the flakes of natural graphite. These flakes are chemically expanded or are treated with high temperature to enhance flexibility of produced sealing component. Graphite seal is well known for its low thermal expansion rate. Seal of graphite is preferred over sealing components made of other materials for its high temperature proof design and exceptional heat sensitivity level. Moreover, its heat transferring capacity is also good.
