568-263 URETHANE 70 DURO ORINGS

U70263 is an AS568-263 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 7.234 in (183.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.512 in (190.8 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The compound resists ozone, extrusion under high pressure, and impact and shock loading. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where prolonged humidity at elevated temperature or acids and bases are present.

Common environments for this compound include mining and heavy equipment, off-highway equipment, and high-pressure fluid power.

This item is sold individually under part number U70263. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
