Factory High Quality Custom Rubber O-Rings made from FKM, NBR, EPDM, and Silicone materials are precision-manufactured sealing components designed for a wide range of applications across numerous industries.
Materials Used:
FKM (Fluoroelastomer): Known for its excellent resistance to heat, oil, and aggressive chemicals. It performs well in temperatures ranging from -15°C to +200°C, and some grades can withstand even higher temperatures.
NBR (Nitrile Butadiene Rubber): Offers superior resistance to petroleum-based oils, fuels, and aliphatic hydrocarbons. It is suitable for temperatures between -40°C and +120°C.
EPDM (Ethylene Propylene Diene Monomer): Provides good resistance to water, steam, and weak acids/bases. It has a temperature range of -50°C to +150°C.
Silicone Rubber: Known for its excellent thermal stability, resistance to UV radiation, and ozone. It works well in temperatures ranging from -60°C to +200°C.
Custom rubber O-rings allow for specific design parameters based on the application requirements. These include:
Size and Dimensions: Tailored to fit unique sealing spaces.
Hardness: Adjusted according to the sealing pressure and environment.
Color: Custom colors may be requested for identification purposes.
Compound Formulation: Modified for specific chemical resistance or temperature ranges.
Custom rubber O-rings find applications in various sectors:
Automotive Industry: Seals for engine compartments, fuel systems, and braking systems.
Aerospace: Sealing components in aircraft engines and hydraulic systems.
Medical Devices: Seals in equipment requiring biocompatibility and sterilization.
Food Processing: Seals that meet food-grade standards.
Chemical Processing: Seals resistant to harsh chemicals and solvents.
