An expansion hole 11 is longitudinally opened inside the installation side 4. The support spring column 7 is located inside the expansion hole 11. Through the combined setting of the ferrule body 2, the widened wear-resistant ring 3, the installation side 4 and the sealing convex ring 5, the rubber ring body 1 as a whole can be used as a ferrule and a washer, so that the connection and sealing performance of the rubber ring body 1 is better. The widened wear-resistant ring 3 and the sealing convex ring 5 can increase the wear resistance at the connection of the rubber ring body 1.
