Part number U70113 is an AS568-113 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists impact and shock loading, abrasion and wear, and extrusion under high pressure. Polyurethane (AU/EU) is known for very high tensile strength and load capacity, exceptional abrasion resistance. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where acids and bases or prolonged humidity at elevated temperature are present.
Maintenance and OEM teams specify it across hydraulic cylinders, mining and heavy equipment, and construction machinery.
Reference part number U70113 when ordering; the item is sold individually. Nominal inside diameter is listed as 9/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
