High-temperature and oil resistance: In high-temperature, high-oil environments such as engines and transmissions, rubber rings maintain long-term elasticity and prevent fluid leakage, ensuring stable powertrain operation.

Vibration-resistant sealing: Withstand continuous vibration and impact during vehicle operation, maintaining sealing integrity without loosening or failure.

Wide temperature range adaptability: From severe winter cold to summer heat, rubber rings perform consistently, ensuring safe vehicle operation under various climatic conditions.
