Piston Seal

WSI Piston Seals are high-performance solutions designed for reciprocating motions in hydraulic and pneumatic cylinders. Engineered to prevent fluid leakage across the piston head, our seals ensure maximum volumetric efficiency and stable linear movement. With superior wear resistance and low-friction properties, WSI provides reliable sealing performance even under extreme pressure cycles.

This series is crafted from premium TPU, PTFE, or high-modulus elastomers to provide excellent anti-extrusion and sealing integrity at high pressures. The specialized profile design minimizes stick-slip effects and reduces heat buildup, significantly extending the service life of both the seal and the cylinder. Each WSI piston seal is precision-manufactured to guarantee tight tolerances and consistent performance in demanding industrial and automotive applications.
