*568-326 URETHANE 90 ORINGS

Ordered as U90326, this is an AS568-326 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 1.6 in (40.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.02 in (51.31 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. This material stands up to petroleum oils, abrasion and wear, and extrusion under high pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

You will find this material specified across off-highway equipment, hydraulic cylinders, and construction machinery.

U90326 ships individually. Nominal inside diameter is listed as 1 5/8 inch. Review your operating media and conditions against this specification before installation.
