-007 BLACK EPDM 70D NSF O-RING

The E70NSF007 is an AS568-007 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 0.145 in (3.68 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.285 in (7.24 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against dilute acids and alkalis, water and steam, and phosphate ester hydraulic fluids. That behavior comes from the compound itself: EPDM (EPR) is valued for outstanding weather, ozone and sunlight resistance, 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 mineral oil-based lubricants or aromatic hydrocarbons call for a different compound.

The compound meets FDA requirements for food contact and carries NSF listing. Typical settings include potable water applications, water and steam systems, and brake and phosphate ester systems.

Reference part number E70NSF007 when ordering; the item is sold individually. Unit weight is approximately 0.051 g.
