568-313 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90313, an AS568-313 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists petroleum oils, extrusion under high pressure, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

Common environments for this compound include off-highway equipment, hydraulic cylinders, and construction machinery.

Stocked as U90313 and sold individually. 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.
