The E70385 is an AS568-385 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 15.955 in (405.26 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 16.375 in (415.93 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to phosphate ester hydraulic fluids, dilute acids and alkalis, and ozone, UV and weathering. EPDM (EPR) is widely chosen for excellent hot water and steam resistance, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It is not the right choice where mineral oil-based lubricants or petroleum oils and fuels are present.

Maintenance and OEM teams specify it across solar and roofing assemblies, outdoor equipment, and brake and phosphate ester systems.
