568-351 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90351, an AS568-351 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to extrusion under high pressure, petroleum oils, and impact and shock loading. Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where acids and bases or prolonged humidity at elevated temperature are present.

Typical settings include mining and heavy equipment, high-pressure fluid power, and hydraulic cylinders.

Stocked as U90351 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
