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 | 36 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 | 45 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.
Urethane Material | 50 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.
Urethane Material | 100 MM Nominal Inner Diameter | Buffer Seal
See Caterpillar® heading in kit catalog for more Caterpillar® replacement parts.
92A Durometer | Urethane Material | 1 3/4 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.
Urethane Material | 2 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 | 100 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 | 50 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 | 70 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.
