For linear and reciprocating dynamic sealing applications

Buffer Rings buffer the pressure spikes of hydraulic systems. They act as a primary rod seal, and at the same time enable trapped fluid sealed by the secondary seal, which is down stream of the buffer, to be pumped back into the system. When a buffer ring is used in combination with a lip seal, the resulting sealing system provides long life with an exceptionally dry rod. Buffer seals are commonly used for rod seal application only.
