*568-134 URETHANE 90 ORINGS - PREM GRADE

U90134 is an AS568-134 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 1.862 in (47.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.068 in (52.53 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance, very high tensile strength and load capacity. The compound resists abrasion and wear, ozone, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in hot water and steam or prolonged humidity at elevated temperature.

Typical settings include off-highway equipment, hydraulic cylinders, and mining and heavy equipment.

U90134 ships individually. Nominal inside diameter is listed as 1 7/8 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.
