568-150 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90150, an AS568-150 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 2.862 in (72.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.068 in (77.93 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The compound resists petroleum oils, impact and shock loading, and ozone. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or ketones.

Maintenance and OEM teams specify it across high-pressure fluid power, hydraulic cylinders, and construction machinery.

This item is sold individually under part number U90150. Nominal inside diameter is listed as 2 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
