-017 BLACK EPDM 70D NSF O-RING

Ordered as E70NSF017, this is an AS568-017 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 0.676 in (17.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.816 in (20.73 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to phosphate ester hydraulic fluids, dilute acids and alkalis, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) delivers outstanding weather, ozone and sunlight resistance, excellent hot water and steam resistance. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Verify compatibility before use with mineral oil-based lubricants or petroleum oils and fuels.

This item meets FDA requirements for food contact and carries NSF listing. Maintenance and OEM teams specify it across potable water applications, water and steam systems, and outdoor equipment.

E70NSF017 ships individually. Unit weight is approximately 0.1734 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
