Rod and buffer seals for fluid power cylinders and actuators seal the applied system pressure against the atmosphere side. Rod seals have a sensible functionality, because if leakage occurs externally, it may contaminate the ambient environment. They are available as single-acting and double-acting seals, but are ideally used as single-acting seals. A wide range of compound and profile configurations is available to meet the user´s specific application profile. They typically interact with wiper elements in the cylinder head sealing system.
