Ordered as U70413, this is an AS568-413 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to extrusion under high pressure, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.
You will find this material specified across press and forming equipment, mining and heavy equipment, and off-highway equipment.
U70413 ships individually. Nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
