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 | 3 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 | 75 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 | 95 MM Nominal Inner Diameter | Buffer Seal

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

Urethane Material | 35 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 | 20 MM Nominal Inner Diameter | Buffer Seal

The RBS style rod buffer seals are a rectangular urethane buffer ring designed to absorb pressure fluctuations to protect the primary rod seal. Some sizes include a radial and axial slot, which faces the pressure, to relieve back pressure between the primary and buffer seal. This simple design is commonly found on older construction equipment.
