Hydraulic Buffer Seals – Shock-Absorption for Rod Seal Protection

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 | 56 MM Nominal Inner Diameter | Buffer Seal

These lip-type buffer seals are designed for replacement in Caterpillar® cylinders. The hinged-lip design reduces friction, heat, and wear under low-pressure conditions and acts as a check valve allowing back-pressure relief. Seals for rod sizes 2-1/8” and under do not have a back-up ring.

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. Bronze-filled Teflon rod buffer seal with a rubber energizer.

Bronze Filled PTFE 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 | 150 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. Bronze-filled Teflon rod buffer seal with a rubber energizer.

Bronze Filled PTFE Material | 5 1/2 in Nominal Inner Diameter | Buffer Seal

See Caterpillar® heading in kit catalog for more Caterpillar® replacement parts.

Bronze Filled PTFE Material | 2 1/2 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 | 60 MM Nominal Inner Diameter | Buffer Seal

These lip-type buffer seals are designed for replacement in Caterpillar® cylinders. The hinged-lip design reduces friction, heat, and wear under low-pressure conditions and acts as a check valve allowing back-pressure relief. Seals for rod sizes 2-1/8” and under do not have a back-up ring.

Urethane Material | 1 1/2 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. Bronze-filled Teflon rod buffer seal with a rubber energizer.

Bronze Filled PTFE Material | 1 3/8 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 | 40 MM Nominal Inner Diameter | Buffer Seal
