PTFE graphite packing (also known as Black PTFE packing) is a resin with PTFE seal made of graphite composite packing, graphite and PTFE as a result have a good self-lubricating properties, and its products very low coefficient of friction, but also a significant reduction in the replacement of the sleeve, due to excellent thermal conductivity of graphite, so that to extend the service life of packing and does not reduce their resistance to chemical media applications. 

       Widely used in petroleum, chemical, electric power, papermaking, printing and dyeing industrial equipment such as pumps, valves, flange sealing.
