Zusammenfassung:	The utility model relates to a sealing part, in particular to a sealing ring with a main lip integrated with an auxiliary lip, which comprises a framework and a sealing piece. The sealing ring is characterized in that the main sealing lip and the auxiliary sealing lip are adhered with the rubber sealing piece to form an integral one-piece PTFE (polytetrafluoroethylene) sheet structure by means of one-step vulcanization forming. An original sealing ring is modified, so that the sealing ring with the main lip integrated with the auxiliary lip has the advantages of simplicity in manufacturing process, low cost, reliable sealing and high work efficiency, is excellent in abrasion resistance, high-temperature resistance and resistance to corrosion of various chemical media, and can meet requirements of actual conditions.
