568-146 URETHANE 90 ORINGS -PREM GRADE

The U90146 is an AS568-146 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 2.612 in (66.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.818 in (71.58 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to ozone, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for exceptional abrasion resistance and long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.

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

Order part number U90146, sold individually. Nominal inside diameter is listed as 2 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
