Part number U70321 is an AS568-321 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 1.162 in (29.51 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.582 in (40.18 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. It resists abrasion and wear, extrusion under high pressure, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

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