*568-131 URETHANE 70 DURO ORINGS

The U70131 is an AS568-131 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 1.674 in (42.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.88 in (47.75 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service and exceptional abrasion resistance. It resists impact and shock loading, extrusion under high pressure, and ozone. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with ketones or prolonged humidity at elevated temperature.

Typical settings include hydraulic cylinders, high-pressure fluid power, and construction machinery.

U70131 ships individually. Nominal inside diameter is listed as 1 11/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. 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.
