-043 BLACK EPDM 70D O-RING

Part number E70043 is an AS568-043 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 3.489 in (88.62 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.629 in (92.18 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists brake fluid, phosphate ester hydraulic fluids, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for strong performance in outdoor and exposed installations, good electrical insulating characteristics. Published continuous service range is -65°F (-53.9°C) to 300°F (148.9°C). Exposure to aromatic hydrocarbons or petroleum oils and fuels will shorten service life.

It sees regular use in solar and roofing assemblies, brake and phosphate ester systems, and water and steam systems.

E70043 ships individually. Unit weight is approximately 0.8259 g and nominal inside diameter is listed as 3 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
