EPDM O-Rings

This product also has outstanding water and steam resistance, showing no swelling or deformation even after long-term immersion or contact with hot water or coolant. The hardness range is mostly between 60-80 Shore A, and black and other color options are available to meet identification needs for different installation environments.

EPDM O-Rings are widely used at flange connections in municipal water supply pipelines and wastewater treatment equipment, as well as for sealing water pumps and thermostat housings in automotive engine cooling systems. With their good weather resistance, they are the preferred weather-resistant sealing material for outdoor engineering and automotive cooling systems.

Compared with nitrile rubber, EPDM material is not resistant to mineral oil, so it is more suitable for water-based or steam media environments. When selecting materials, customers are advised to confirm the type of contact media in advance to avoid sealing failure caused by material mismatch; we can assist with material selection recommendations.
