Buffer Seals

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 | 45 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 | 3 in 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 | 3 1/2 in Nominal Inner Diameter | Buffer Seal

Molded in bronze-filled PTFE with an FKM energizer, this seal is used to protect the primary seal from damage caused by pressure spikes and excessive heat build up. Bronze-filled Teflon rod buffer seal with a Viton energizer.

Bronze PTFE Buffer Material | 1 3/4 in Nominal Inner Diameter | Buffer Seal

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

Urethane Material | 56 MM Nominal Inner Diameter | Buffer Seal

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

Urethane Material | 56 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 | 150 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 | 56 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. 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 | 90 MM Nominal Inner Diameter | Buffer Seal
