EPDM (Ethylene Propylene Rubber)

Categories: ,


Ethylene Propylene Rubber with the addition of a Diene Monomer. These materials are particularly useful when sealing against phosphate-ester hydraulic fluids and for glycol based fluids.

Temperature Range

-57°C to +150°C


Applications include seals used in hydraulic and braking systems.


  • Excellent resistance to steam and hot water
  • Good ozone resistance
  • Excellent resistance to glycol based break fluids and phosphate-esters
  • Not compatible with mineral oils or petroleum based fluids
