568-244 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-244 clear Polyurethane (AU/EU) 90 Shore A supplied with an inside diameter of 4.234 in (107.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.512 in (114.6 mm), catalogued under part number U90244. It remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The material holds up against ozone, extrusion under high pressure, and abrasion and wear. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across high-pressure fluid power, press and forming equipment, and construction machinery.

This item is sold individually under part number U90244. Nominal inside diameter is listed as 4 1/4 inch. Review your operating media and conditions against this specification before installation. 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.
