The COP/APA Fluorine Rubber Double-acting Cylinder Piston Seal is a premium sealing solution engineered for the most demanding industrial applications. Manufactured from high-grade Fluoroelastomer (FKM), this specialized O-ring delivers exceptional performance in extreme temperatures, aggressive chemicals, and high-pressure environments, ensuring reliable sealing in both stroke directions of double-acting cylinders.

1.Material Performance: Strong material properties, with excellent resistance to high and low temperatures (-20°C to 200°C), strong acids, strong alkalis, and various oils, as well as outstanding chemical stability, making it less prone to swelling and cracking.
2. Good Sealing Effect: Well-suited for the reciprocating motion of double-acting cylinders, it conforms closely to the sealing surface, minimizes leakage under high pressure, has low compression deformation, and ensures long-term reliable sealing.
3. Outstanding Durability: High wear resistance and tear resistance, with good ozone aging resistance. Its lifespan is 3-5 times that of ordinary rubber rings, reducing replacement frequency.
4. High Adaptability and Cost-Effectiveness: Precisely matches the operating conditions of APA double-acting cylinders, reduces equipment maintenance costs, and can be used in multiple high-end scenarios such as chemical industry, machine tools, and automobiles.
