Compression set resistant piston seals are engineered to withstand prolonged compression without losing their original shape or sealing effectiveness. In hydraulic systems operating under continuous load or extended dwell times, compression set resistance is critical for preventing leakage and maintaining pressure integrity. These seals are manufactured using advanced elastomers and optimized formulations that recover after compression cycles. Compression set resistant piston seals are widely used in industrial machinery, mobile hydraulics, and energy equipment where reliability and low maintenance are essential.
