High-Performance EPDM O-Rings: Engineered for Extreme Weathering & Steam Resistance
OringWorld provides precision-engineered Ethylene Propylene Diene Monomer (EPDM) O-rings designed for critical industrial applications. Our seals offer unmatched durability against ozone, UV exposure, and high-temperature steam.
The EPDM Advantage: Superior Environmental Sealing
EPDM (Ethylene Propylene Diene Monomer) is a high-density synthetic rubber characterized by its exceptional resistance to environmental stressors. Unlike nitrile (NBR), EPDM maintains its physical properties when exposed to harsh outdoor conditions and polar solvents.

Frequently Asked Questions
Can EPDM O-rings be used with petroleum-based oils?
No. EPDM has poor resistance to petroleum oils, greases, and fuels. For these applications, we recommend our Nitrile (NBR) or Viton (FKM) solutions.
What is the difference between Peroxide and Sulfur curing?
Peroxide-cured EPDM offers better heat resistance and a lower compression set, making it ideal for high-temperature steam applications. Sulfur-cured EPDM is more cost-effective and offers better tear resistance.
