About epdm ethylene propylene diene monomer.
Epdm o rings for brake fluid.
Of these three rubber types epdm is the only choice for seals in braking systems using a glycol based or silicone based dot approved or pure racing brake fluid.
These compounds also withstand the effect of brake fluids and skydrol and other phosphate ester based hydraulic fluids.
Parker s ethylene propylene rubber epm epr epdm o rings are compatible with solvents and other chemicals.
Our stock o ring compounds are made with an amount of a third diene monomer ethylene propylene diene terpolymers.
Made of epdm they resist water steam ethanol and ethylene glycol.
Ethylenepropylene diene rubber epdm produced using a third monomer and is particularly useful when sealing phosphate ester hydraulic fluids and in brake systems that use fluids having a glycol base.
Epdm has a great acceptance in the sealing world because of its excellent resistance to heat water and steam alkali mild acidic and oxygenated solvents ozone and sunlight uv.
If a seal is made for automotive brake systems and the material is not specified you can safely assume it is epdm.
Use these o rings with metric sanitary fittings which are also called aseptic fittings.
