Rod Seals

Parker rod seals for hydraulic and pneumatic cylinders and actuators seal the applied system pressure against the atmosphere side. Their purpose is to prevent external leakage and thus avoid contamination of the ambient environment. They are available as single-acting and double acting seals. High-pressure applications usually require a tandem rod sealing system including a buffer seal. Rod seals typically interact with wiper elements in the cylinder sealing system. A wide range of compound and profile configurations is available to meet the specific application profile. There are rod seals available that comply with ISO 6020, ISO 5597 and ISO 7425-2 standards.
