-415 BLACK EPDM 70D O-RING

Ordered as E70415, this is an AS568-415 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 3.225 in (81.92 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.775 in (95.89 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against ketones, brake fluid, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is valued for good electrical insulating characteristics, outstanding weather, ozone and sunlight resistance. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Applications involving petroleum oils and fuels or aromatic hydrocarbons call for a different compound.

It sees regular use in HVAC and refrigeration, brake and phosphate ester systems, and outdoor equipment.
