AS016-70EP EPDM O-Ring AS568-016

Ethylene-propylene diene (EPD) is usually compounded with a third monomer to produce what is most commonly referred to as EPDM rubber. EPDM o-rings are frequently used to seal brake systems and in many hot water and steam applications. Additionally, EPDM compounds have good resistances to; mild acids, detergents, alkalis, silicone oils and greases, ketones, and alcohols. EPDM has gained wide acceptance in the o-ring and rubber seal industry due to these excellent chemical resistance properties and its superior ozone resistance. In applications with petroleum oils, mineral oil, die-ester lubricants or fuel exposure EPDM is not recommended. EPDM is sometimes referred to by the following trade names; EP, EPT or EPR.

The EPDM AS016-70EP o-ring can be reference in one of four ways:

  • Mostly commonly, the industry standard AS568 “dash” number: (AS568-016)
  • Standard dimensions: (CS 0.070" x ID 0.614")
  • Metric dimensions: (CS 1.78 x ID 15.60)
  • Nominal fractional dimensions: (CS 1/16 " x ID 5/8")

The final consideration for an o-ring after size and material type is the durometer. Durometer is an industry standard measurement for a material’s hardness. Most often for rubber seals, durometer is measured and listed in accordance with the “Shore A” scale. Typical durometers for standard rubber seals are 70, 75 and 90, depending on the material. A higher number indicates a harder material. Durometer is also generally stated and accepted with a “+/- 5” tolerance. For EPDM o-rings, the standard nominal durometer is 70.
