EPDM O-rings are elastomeric sealing rings made from ethylene–propylene–diene rubber (EPDM), designed for applications requiring excellent resistance to hot water, steam, polar solvents and environmental exposure. EPDM offers outstanding stability against ozone, UV radiation, weathering and ageing, making it one of the most reliable materials for outdoor and water-based systems.
Depending on the curing system (sulphur or peroxide), EPDM provides a broad operating range of –55 °C to +150 °C and maintains elasticity even at low temperatures. The material is also fully compatible with brake fluids (DOT 3/4), silicone oils, many acids, alkaline solutions and glycol-based fluids.
However, EPDM is not resistant to mineral oils, petroleum greases, fuels or hydrocarbon-based fluids. For oil and fuel systems, NBR (Buna-N / Buna-M / МБР) or FKM/FPM/Viton should be used instead.
Key Advantages:
• excellent resistance to hot water and steam
• outstanding ozone, UV and weathering resistance
• good resistance to polar solvents, acids and bases
• compatible with silicone oils and brake fluids (DOT 3/4)
• wide temperature range –55…+150 °C
• long service life in outdoor and water-based applications
Typical Applications:
• water and steam systems
• pumps, valves, pipe fittings
• heating and cooling equipment
• automotive brake systems (DOT 3/4)
• chemical process and laboratory equipment
• food and medical equipment (depending on compound)
• outdoor installations exposed to ozone and sunlight
EPDM O-rings are the preferred choice for environments involving water, steam, chemicals or atmospheric exposure—where resistance to oils and fuels is not required.
