Part number U90044 is an AS568-044 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 3.739 in (94.97 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.879 in (98.53 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to extrusion under high pressure, ozone, and abrasion and wear. Polyurethane (AU/EU) is valued for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in ketones or acids and bases.
Common environments for this compound include press and forming equipment, construction machinery, and hydraulic cylinders.
Stocked as U90044 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
