This U-cup style buffer ring offers an asymmetric sealing lip profile, chamfered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. This rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions thus increasing the life of the primary seal.
Urethane Material | 3 in Nominal Inner Diameter | Buffer Seal
Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.
Urethane Material | 63 MM Nominal Inner Diameter | Buffer Seal
Molded in PTFE with a rubber energizer, this seal absorbs the shock of pressure spikes to protect the rod seal.
