Epdm O Ring Specifications

Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications.

Epdm o ring specifications. Epdm offers outstanding resistance to weather heat and ozone. Buna n and viton o rings can be used for sealing valves faucets flanges engines and more. We supply epdm o rings epdm seals and epdm gaskets in standard as568 sizes and in custom configurations to match your design needs. These compounds also withstand the effect of brake fluids and skydrol and other phosphate ester based hydraulic fluids.

The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene. This is particularly useful when sealing phosphate ester hydraulic fluids and in brake systems that use fluids having a glycol base. Choose from our selection of epdm rubber o rings including over 700 products in a wide range of styles and sizes. Epdm is an m class rubber under astm standard d 1418.

Parker s 80 durometer black epdm em163 80 is a terpolymer of ethylene and propylene with a diene third monomer used for cross linking. 0 239 x 0 070 70 bn. Finding the correct material especially if you are using it for an o ring seal is important as the rubber can degrade quickly if the material is not. Thus for an as568 010 size 70 shore a nitrile would be.

O rings are typically called out by the inner diameter of the torus and the diameter of the round cross section. In stock and ready to ship. It is also compatible with ketones fireproof hydraulic fluids alkalis and water. If you need epdm properties that are different than the ones shown in the chart below we can reformulate the compound of the epdm material so that the epdm rubber specifications suit your needs.

Parker s ethylene propylene rubber epm epr epdm o rings are compatible with solvents and other chemicals. Epdm is made from ethylene propylene and a diene comonomer that enables. 900 series o rings feature a round cross section. 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.

Speak with a product expert. Technical specifications polymer material options. About epdm ethylene propylene diene monomer. For standard sizes aerospace standard as568 and iso 3601 for metric sizes are used to give the dimension and tolerance.

Epdm o rings feature lower cost steam and chemical resistance for numerous applications.
