Ordered as U70112, this is an AS568-112 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Polyurethane (AU/EU) is specified for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Expect good resistance to impact and shock loading, abrasion and wear, and ozone. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Exposure to hot water and steam or prolonged humidity at elevated temperature will shorten service life.
Maintenance and OEM teams specify it across press and forming equipment, hydraulic cylinders, and high-pressure fluid power.
Reference part number U70112 when ordering; the item is sold individually. Nominal inside diameter is listed as 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
