This o-ring is supplied in AS568-354 clear Polyurethane (AU/EU) 90 Shore A with an inside diameter of 5.1 in (129.54 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.52 in (140.21 mm), catalogued under part number U90354. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against impact and shock loading, ozone, and petroleum oils. Polyurethane (AU/EU) is known for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It is not the right choice where acids and bases or prolonged humidity at elevated temperature are present.

It sees regular use in mining and heavy equipment, high-pressure fluid power, and press and forming equipment.
