-228 BLACK EPDM 70D O-RING

Part number E70228 is an AS568-228 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 2.234 in (56.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.512 in (63.8 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists phosphate ester hydraulic fluids, water and steam, and ozone, UV and weathering. EPDM (EPR) is widely chosen for good electrical insulating characteristics and very good flexibility at low temperature. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Applications involving mineral oil-based lubricants or petroleum oils and fuels call for a different compound.

You will find this material specified across brake and phosphate ester systems, potable water applications, and outdoor equipment.
