Epdm O Rings For Brake Fluid

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 o rings for brake fluid.

If you buy your brake fluid from pegasus auto racing supplies use epdm seals in that system don t panic most companies that make master cylinder and caliper seals only offer them in an epdm version. These compounds also withstand the effect of brake fluids and skydrol and other phosphate ester based hydraulic fluids. If a seal is made for automotive brake systems and the material is not specified you can safely assume it is epdm. O ring compatibility plays a critical role in o ring performance â find the right material for your application and avoid o ring failures.

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. Our stock o ring compounds are made with an amount of a third diene monomer ethylene propylene diene terpolymers.

Parker s ethylene propylene rubber epm epr epdm o rings are compatible with solvents and other chemicals.

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.
