A pliable, non-metallic PU ring is ingeniously nestled within a precision-machined groove or seamlessly integrated into a composite of rings, forming a robust sealing assembly. Essential in converting fluid power to linear motion, it adeptly impedes or segregates fluid flow in reciprocating machinery.    

Advantage

Main specifications: Available in a variety of sizes, colors and materials

Remains resilient at low temperatures

Resistant to hydrocarbon fuels and petroleum

Low compressive deformation rate

Excellent wear resistance and tensile strength, good elasticity, easy to install

Ideal for hydraulic applications with high pressure, dust contamination and shock absorption.
