This single-acting rod buffer seal is designed to be used in conjunction with a rod seal to protect the primary seal from shock pressure loading and high frequency pressure spikes in the hydraulic system. The design allows oil to pass through to the rod seal while holding back pressure spikes. The seal is an excellent pressure buffer option in heavy-duty applications and offers extended sealing system life and performance. The seal is moulded in polyurethane, for easy installation and excellent low temperature performance. The design incorporates a polyacetal anti-extrusion ring to provide maximum extrusion resistance against shock pressure loads.
