It consists of a filled PTFE wear ring and an O-ring rubber sealing ring. The O-ring provides radial preload and can compensate for wear of the wear ring. It has a two-way sealing effect and can withstand pressure in one or two directions. It is suitable for hole sealing of shafts, rods, bearings, rotary joints, swivel seats, etc. that rotate at high pressure and low speed. If the hole diameter is smaller than Φ40, the split groove should be used.
