SKF GS 63X78.5X6.3-AD1 Single-acting step style piston buffer seal with PTFE seal ring and nitrile energizer

GS seals are single-acting, step style piston buffer seals with a PTFE slide ring and a nitrile rubber O-ring energizer. The seals are suitable for applications with high demands on sealing ability, and have the ability to handle pressure spikes and protect the primary piston seal. They may be used in double-acting cylinders when using two seals in a back-to-back arrangement.
