Polytetrafluoetylene oil seal

The utility model relates to the technical field of reciprocating and rotating oil seals, in particular to a polytetrafluoetylene oil seal. The oil seal comprises a frame, a rubber body and a polytetrafluoetylene clip, wherein the rubber body is wrapped on the frame; the polytetrafluoetylene clip and the rubber body are bonded closely; reflow patterns rotating in the same direction with the axle rotating direction are formed on both sides of the polytetrafluoetylene clip; and oil stop blocks preventing oil from exosmosis are arranged in continuous grooves of the reflow patterns. The polytetrafluoetylene oil seal has the advantages of simple structure, easy manufacture and lower cost, improves the flexibility and dynamic following performance of the polytetrafluoetylene clip, and effectively eliminates the potential hazard of static oil leakage.
