Standard Buffer Seals


Our Standard Buffer Seals protect rod seals from pressure spikes, providing secondary sealing. Our PTFE rod contact surface provides low friction and a long seal life. The buffer seals also vent back pressure. The heavy-duty rod seal is ideal for medium duty cycle applications requiring low friction and service at extreme temperatures.

They're filled with PTFE and Nitrile.
