-333 BLACK EPDM 70D NSF O-RING

E70NSF333 is an AS568-333 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 2.475 in (62.87 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.895 in (73.53 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

EPDM (EPR) is specified here for excellent hot water and steam resistance, good electrical insulating characteristics. The compound resists brake fluid, phosphate ester hydraulic fluids, and dilute acids and alkalis. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with mineral oil-based lubricants or aromatic hydrocarbons.

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across solar and roofing assemblies, brake and phosphate ester systems, and potable water applications.
