E70417 is an AS568-417 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The compound resists water and steam, phosphate ester hydraulic fluids, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is specified for good electrical insulating characteristics, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Exposure to mineral oil-based lubricants or aromatic hydrocarbons will shorten service life.
It sees regular use in outdoor equipment, potable water applications, and water and steam systems.
Order part number E70417, sold individually. Unit weight is approximately 13.086 g.
