Polyurethane Buffer Seals


Polyurethane Buffer Seals are produced from a tough and durable urethane and incorporate an anti-extrusion ring for high pressures. Commonly used in fluid power applications, these Buffer Seals can handle high pressure spikes, internal system contamination and vent back pressure. With the designed standoff pedestals and notches, back pressure will never become trapped between this Buffer Seal and the rod seal, ensuring a long life for the application.
