568-443 URETHANE 90 ORINGS -PREM GRADE

U90443 is an AS568-443 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 7.475 in (189.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.025 in (203.84 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists abrasion and wear, petroleum oils, and impact and shock loading. Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

You will find this material specified across hydraulic cylinders, press and forming equipment, and high-pressure fluid power.

U90443 ships individually. 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.
