568-151 URETHANE 70 DURO ORINGS

APG stocks the U70151, an AS568-151 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 2.987 in (75.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.193 in (81.1 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is specified here for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. This material stands up to petroleum oils, 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).

Common environments for this compound include high-pressure fluid power, hydraulic cylinders, and press and forming equipment.

U70151 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
