The U70371 is an AS568-371 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 8.475 in (215.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.895 in (225.93 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Polyurethane (AU/EU) is specified for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. The compound resists abrasion and wear, impact and shock loading, and petroleum oils. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Verify compatibility before use with ketones or prolonged humidity at elevated temperature.
It sees regular use in press and forming equipment, hydraulic cylinders, and high-pressure fluid power.
Stocked as U70371 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
