摘要： An improved composite seal ring is provided by making the L-shaped main seal ring and auxiliary seal ring of a thermoplastic or thermosetting synthetic resin and the ratio of the axial thickness of the thin wall portion of the main seal ring to the axial thickness of the entire composite seal ring being between 1/2 and 3/4 and the auxiliary seal ring having a radial width at least twice as large as the piston-cylinder gap and less than 4/5 the radial width of the entire composite seal ring.
