568-375 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90375, an AS568-375 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 9.475 in (240.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.895 in (251.33 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. Expect good resistance to ozone, abrasion and wear, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving ketones or prolonged humidity at elevated temperature call for a different compound.

It sees regular use in off-highway equipment, mining and heavy equipment, and press and forming equipment.

U90375 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
