Consists of a filled PTFE slip ring and an O-ring rubber seal. The O-ring provides radial preload so that the slip ring wraps around the shaft and compensates for wear of the wear ring. With double-sided sealing effect, it can withstand pressure in one or two directions. It is suitable for shafts, rods, bearings, rotary joints, swivel seats, etc. that rotate at high pressure and low speed. If the shaft diameter is smaller than Φ30, the split groove should be used.
