Bronze Filled PTFE Material | 2 3/8 in Nominal Inner Diameter | Buffer Seal
With a wider temperature range and a higher pressure rating than the standard DYR style, the DYR-BR43 rod buffer seal 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.
90A Durometer | Urethane Material | 2 1/2 in Nominal Inner Diameter | Buffer Seal
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.

92A Durometer | Urethane Material | 1 1/4 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 | 20 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 | 22 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. Designed to allow for back-pumping capabalities while improving wear resistance and decreasing friction. Can be used as a secondary seal or in tandem with a PTFE buffer seal.
58D; 70A Durometer | Urethane Material | 60 MM Nominal Inner Diameter | Buffer Seal
Molded in polyurethane, this buffer seal is a simple flat, washer-like profile.
Urethane Material | 25 MM Nominal Inner Diameter | Buffer Seal
