568-463 URETHANE 70 DURO ORINGS

APG stocks the U70463, an AS568-463 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists abrasion and wear, ozone, and extrusion under high pressure. Polyurethane (AU/EU) delivers very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where acids and bases or ketones are present.

It sees regular use in press and forming equipment, hydraulic cylinders, and off-highway equipment.

This item is sold individually under part number U70463. Nominal inside diameter is listed as 17 inch. Check the compound against your process media, pressure and temperature before committing to a design.
