Buffer Seals

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 | 8 in 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.

70A Durometer | Filled PTFE Buffer Material | 18 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.

70A Durometer | Filled PTFE Buffer Material | 40 MM Nominal Inner Diameter | Buffer Seal

Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.

Urethane Material | 70 MM Nominal Inner Diameter | Buffer Seal

Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.

Urethane Material | 70 MM Nominal Inner Diameter | Buffer Seal

Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.

Urethane Material | 75 MM Nominal Inner Diameter | Buffer Seal

Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.

Urethane Material | 80 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.

70A Durometer | Filled PTFE Buffer Material | 130 MM Nominal Inner Diameter | Buffer Seal

Molded in urethane and employing a back-up, this seal absorbs the shock of pressure spikes to protect the rod seal. The unique design relieves back pressure between the buffer and the rod seal. NOTE: ME = Merkel Equivalent.
