The U90034 is an AS568-034 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 2.114 in (53.7 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.254 in (57.25 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The material holds up against abrasion and wear, extrusion under high pressure, and impact and shock loading. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Verify compatibility before use with ketones or prolonged humidity at elevated temperature.
Common environments for this compound include hydraulic cylinders, construction machinery, and high-pressure fluid power.
Reference part number U90034 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/8 inch. Review your operating media and conditions against this specification before installation.
