EPDM (Ethylene Propylene Diene Monomer) O-rings are made from a synthetic rubber compound known for its excellent resistance to heat, ozone, and weathering. They are commonly used in sealing applications where resistance to water, steam, and a variety of chemicals is required. EPDM O-rings offer outstanding electrical insulation properties and are widely used in automotive, plumbing, and industrial applications.

EPDM Recommended Uses

Seals and gaskets, water and wastewater systems, automotive applications, plumbing systems, steam systems, chemical processing, electrical insulation, general-purpose applications.

EPDM Not Recommended

Oils, fuels, aromatic hydrocarbons, ketones, chlorinated hydrocarbons, and other non-polar solvents.

EPDM Limitations
  • Not suitable for use with oils, fuels, and non-polar solvents.
  • Not ideal for low-temperature environments.
  • Limited resistance to abrasion and wear in certain conditions.
  • Not recommended for applications requiring high compression set resistance.
EPDM Usable Temperature Range

-40 to 250°F (-40 to 121°C)

EPDM Also Known As
