-349 BLACK EPDM 80D O-RING

E80PC349 is an AS568-349 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 4.475 in (113.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.895 in (124.33 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists brake fluid, phosphate ester hydraulic fluids, and ozone, UV and weathering. EPDM (EPR) delivers excellent hot water and steam resistance, very good flexibility at low temperature. Published continuous service range is -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.

It sees regular use in potable water applications, outdoor equipment, and water and steam systems.
