568-412 URETHANE 70 DURO ORINGS

Part number U70412 is an AS568-412 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 2.85 in (72.39 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.4 in (86.36 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. This material stands up to abrasion and wear, ozone, and petroleum oils. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or acids and bases call for a different compound.

It sees regular use in hydraulic cylinders, press and forming equipment, and high-pressure fluid power.

Order part number U70412, sold individually. Nominal inside diameter is listed as 2 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
