-018 BLACK EPDM 70D NSF O-RING

The E70NSF018 is an AS568-018 black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 0.739 in (18.77 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.879 in (22.33 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

EPDM (EPR) is widely chosen for excellent hot water and steam resistance, outstanding weather, ozone and sunlight resistance. Expect good resistance to brake fluid, phosphate ester hydraulic fluids, and ketones. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Verify compatibility before use with petroleum oils and fuels or aromatic hydrocarbons.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across brake and phosphate ester systems, outdoor equipment, and potable water applications.

Order part number E70NSF018, sold individually. Unit weight is approximately 0.0002 g and nominal inside diameter is listed as 3/4 inch.
