1MM CS X 5MM ID BLACK EPDM 70D

Part number E1X5 is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 5 mm (0.197 in), a cross section of 1 mm (0.039 in), and an outside diameter of 7 mm (0.28 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against water and steam, brake fluid, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is known for strong performance in outdoor and exposed installations, excellent hot water and steam resistance. Continuous operating temperature is published at -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.

Maintenance and OEM teams specify it across HVAC and refrigeration, outdoor equipment, and potable water applications.

E1X5 ships individually. Unit weight is approximately 0.0201 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
