Part number U70173 is an AS568-173 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 8.487 in (215.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.693 in (220.8 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 exceptional abrasion resistance. The compound resists petroleum oils, extrusion under high pressure, and ozone. 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 hot water and steam are present.
Typical settings include construction machinery, off-highway equipment, and hydraulic cylinders.
U70173 ships individually. Nominal inside diameter is listed as 8 1/2 inch. Review your operating media and conditions against this specification before installation.
