Buffer seals act as a secondary barrier in hydraulic systems, absorbing pressure spikes and protecting the primary seal from damage. North Coast Seal’s buffer seals provide superior performance under fluctuating pressures and demanding conditions.
Our buffer seals are available in high-performance materials such as polyurethane, PTFE, and rubber fabric composites. These materials resist extrusion and wear, providing a longer service life in hydraulic cylinders and actuators.
