Step Ring for Hole GSD

The piston has a one-way acting seal ring consisting of an anti-wear filled PTFE ring and an O-shaped rubber seal ring. The O-ring provides elasticity, compensates for the wear on the PTFE wear ring, and has a one-way sealing effect. Suitable for sealing the piston of a hydraulic cylinder. A guide ring is generally used.
