Epdm O Ring Specifications

For standard sizes aerospace standard as568 and iso 3601 for metric sizes are used to give the dimension and tolerance.

Epdm o ring specifications.

These compounds also withstand the effect of brake fluids and skydrol and other phosphate ester based hydraulic fluids. Each features a round cross section. This is particularly useful when sealing phosphate ester hydraulic fluids and in brake systems that use fluids having a glycol base. In stock and ready to ship.

Epdm is an m class rubber under astm standard d 1418. Thus for an as568 010 size 70 shore a nitrile would be. 0 239 x 0 070 70 bn. The m class comprises elastomers having a saturated chain of the polyethylene type the m deriving from the more correct term polymethylene.

It is also compatible with ketones fireproof hydraulic fluids alkalis and water. O rings are typically called out by the inner diameter of the torus and the diameter of the round cross section. About epdm ethylene propylene diene monomer. We supply epdm o rings epdm seals and epdm gaskets in standard as568 sizes and in custom configurations to match your design needs.

Epdm is made from ethylene propylene and a diene comonomer that enables. Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications.
