568-320 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90320, an AS568-320 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.1 in (27.94 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.52 in (38.61 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Expect good resistance to ozone, abrasion and wear, and impact and shock loading. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving ketones or acids and bases call for a different compound.

Maintenance and OEM teams specify it across press and forming equipment, off-highway equipment, and high-pressure fluid power.

Stocked as U90320 and sold individually. Nominal inside diameter is listed as 1 1/8 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
