Automotive O-Rings

Automotive O-rings are widely used in vehicles to seal fluids and gases in engines, transmissions, fuel systems, and climate control systems. We supply high-quality automotive O-rings designed to meet demanding performance and durability requirements.

O-Rings for Automotive Applications

Our automotive O-rings are manufactured to precise standards, ensuring reliable sealing under vibration, temperature fluctuations, and exposure to oils, fuels, and coolants.

Common Materials for Automotive O-Rings

• NBR (Buna-N): fuel and oil resistance for general automotive use
• HNBR: improved heat and wear resistance
• FKM (Viton®): excellent high-temperature and chemical resistance
• EPDM: suitable for brake systems and coolant applications
• Silicone: flexibility in low-temperature environments

Typical Automotive Systems

• Engine and transmission sealing
• Fuel injection and fuel delivery systems
• Cooling and air conditioning systems
• Power steering and braking systems
• Electric and hybrid vehicle components
