Part number U70393 is an AS568-393 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. The compound resists ozone, 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). Applications involving hot water and steam or acids and bases call for a different compound.
Maintenance and OEM teams specify it across high-pressure fluid power, construction machinery, and mining and heavy equipment.
Stocked as U70393 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
