What EPDM O-Rings Offer
EPDM (Ethylene Propylene Diene Monomer) O-Rings offer superior resistance to harsh environments with exposure to heat, water, steam, ozone, and UV radiation. They have robust chemical resistance and can handle a broad temperature range, ensuring reliable, long-lasting performance in critical applications.
Features & Benefits:
- Protection Against Harsh Fluids: Provides excellent resistance to brake fluids, SKYdrol®, and hydraulic fluids.
- Water & Steam Resistance: Highly resistant to hot water, steam, and environments with excess moisture.
- Heat Resistance: Capable of withstanding temperatures up to 150°C (302°F).
- Cold Flexibility: Maintains excellent sealing performance even at temperatures as low as -70°F (-57°C).
EPDM O-Rings offer outstanding performance in a range of demanding environments, providing reliable sealing solutions in both high-temperature and low-temperature conditions while resisting water, steam, chemicals, and harsh fluids.
Potential Applications & Industries
EPDM O-Rings are ideal for applications where resistance to water, steam, heat, and UV radiation is critical. This includes:
- Water and wastewater systems: EPDM O-rings resist exposure to moisture and harsh chemicals, ensuring reliable sealing in environments where these conditions are common.
- Medical devices: Non-toxic properties and the ability to withstand repeated sterilization cycles make EPDM O-rings ideal for use in medical applications.
- Braking systems: EPDM O-rings resist degradation from brake fluids, maintaining system reliability under extreme pressure and temperature.
- General applications: EPDM O-rings are well-suited for environments requiring resistance to water, steam, heat, and UV radiation.
EPDM O-Rings are essential in a variety of industries that demand high-performance sealing solutions. Key industries include healthcare, transportation, fluid power, and aerospace. Their chemical resistance and temperature tolerance also make them a reliable choice for industrial and military industries.

Design Specifics & How The Product Works
EPDM O-Rings are engineered for superior sealing performance in both static and dynamic applications. The design includes an elastomeric material that provides an excellent seal by compressing against the sealing surface, preventing leakage while accommodating the movement of rotating or reciprocating parts.
What Makes EPDM O-Rings So Effective? The unique formulation of EPDM O-Rings makes them ideal for applications where other sealing materials might fail due to their inability to withstand extreme environmental factors. Their long-lasting durability ensures that EPDM O-Rings continue to perform over time, protecting vital components from contaminants and maintaining system integrity.
