O Rings

O rings are versatile seals used in a wide range of hydraulic and pneumatic systems. They fit into grooves and compress during assembly to form a tight seal. Made from materials like NBR, FKM, EPDM, and silicone, O rings provide excellent resistance to pressure, temperature, and chemicals. These seals are commonly used in valves, pumps, cylinders, connectors, and flanges across industries such as automotive, machinery, and fluid control. Proper material selection ensures long-term sealing performance and leak prevention.

FEP/PFA Encapsulated O-Rings
Encapsulated O-rings combine an elastomeric core (Silicone/FKM) with a seamless FEP/PFA jacket. This hybrid construction merges universal chemical resistance with high-resilience sealing, significantly outlasting standard rubber seals in extreme thermal and corrosive environments.
