*568-131 URETHANE 90 ORINGS

U90131 is an AS568-131 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 1.674 in (42.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.88 in (47.75 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists petroleum oils, abrasion and wear, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, exceptional abrasion resistance. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Typical settings include off-highway equipment, construction machinery, and mining and heavy equipment.

Order part number U90131, sold individually. Nominal inside diameter is listed as 1 11/16 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
