-220 BLACK EPDM 70D O-RING

Ordered as E70220, this is an AS568-220 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 1.359 in (34.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.637 in (41.58 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

EPDM (EPR) is specified here for very good flexibility at low temperature and good electrical insulating characteristics. The compound resists dilute acids and alkalis, ozone, UV and weathering, and brake fluid. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to petroleum oils and fuels or aromatic hydrocarbons will shorten service life.

Maintenance and OEM teams specify it across HVAC and refrigeration, water and steam systems, and outdoor equipment.

This item is sold individually under part number E70220. Unit weight is approximately 1.5335 g and nominal inside diameter is listed as 1 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
