Part number U90348 is an AS568-348 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 4.35 in (110.49 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.77 in (121.16 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. The material holds up against ozone, impact and shock loading, and petroleum oils. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).
Maintenance and OEM teams specify it across construction machinery, mining and heavy equipment, and high-pressure fluid power.
U90348 ships individually. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
