Graphite PTFE packing, also known as polytetrafluoroethylene graphite packing is made of PTFE threads containing graphite particles. It has a strong tear strength and high thermal conductivity, low friction coefficient in turn make PTFE graphite packing has a stable and long life. Recommended for pump shaft seals, but also for sealing water, steam, solvents and other media stirrer, mixer, autoclave and centrifugal pump.
