Rubber sealing rings are indispensable across multiple industries, with each type of rubber offering distinct advantages. Nitrile Rubber (NBR) stands out for its outstanding oil resistance, making it a top choice for automotive engines, especially in sealing oil pans, transmissions, and fuel lines. Ethylene Propylene Diene Monomer (EPDM) rubber excels in weather resistance, enduring harsh outdoor conditions, and is widely used for roofing and automotive door/window seals.
Rubber Sealing Rings: Material Advantages & Applications
Nitrile Rubber (NBR)
• Superior oil resistance for automotive engine seals (oil pans, fuel lines)
• Abrasion-tolerant for industrial machinery
EPDM
• Exceptional weather resistance for outdoor use (roofing, vehicle door seals)
• Chemical stability suitable for chemical plants
Silicone o-rings
• High-temp tolerance for engines, ovens, and exhaust systems
• Cold flexibility and electrical insulation for electronics
FKM/Viton
• Extreme chemical resistance for pharmaceutical/chemical sectors
• Heat resistance and low gas permeability for aerospace/high-pressure systems
Butyl Rubber
• Ultra-low gas permeability for tire inner tubes and gas tanks
• Vibration damping and water resistance
