RB-NYL-2.500idx2.620odx1.475ht

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 7/8 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. Bronze-filled Teflon rod buffer seal with a rubber energizer.

Bronze Filled PTFE Material | 2 1/4 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 | 5 in Nominal Inner Diameter | Buffer Seal

With a steel body, bronze liner, and PTFE / lead overlay, these bushings possess excellent wearability and tremendous compressive strength.

PTFE/Lead Material | 25 MM Nominal Inner Diameter | Rod Bushing

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

Urethane Material | 30 MM Nominal Inner Diameter | Buffer Seal

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

Urethane Material | 50 MM Nominal Inner Diameter | Buffer Seal

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

Urethane Material | 60 MM Nominal Inner Diameter | Buffer Seal

Molded with a premium urethane and employing a back-up, this seal absorbs the shock of pressure spikes to protect the rod seal. The unique design also relieves back pressure between the buffer and the rod seal. The premium urethane demonstrates good heat resistance with almost no permanent deformation at high temperatures. In addition, the elastomeric properties can be quickly restored even in low temperatures to ensure stable sealing in cold applications.

Urethane Material | 100 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 | 105 MM Nominal Inner Diameter | Buffer Seal
