568-276 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90276, an AS568-276 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 10.984 in (278.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.262 in (286.05 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists petroleum oils, extrusion under high pressure, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) offers 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). Verify compatibility before use with acids and bases or prolonged humidity at elevated temperature.

Typical settings include mining and heavy equipment, press and forming equipment, and construction machinery.

Reference part number U90276 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
