*568-346 URETHANE 90 ORINGS PR GRADE

Part number U90346 is an AS568-346 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 4.1 in (104.14 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.52 in (114.81 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to ozone, abrasion and wear, and impact and shock loading. Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in ketones or prolonged humidity at elevated temperature.

Common environments for this compound include high-pressure fluid power, off-highway equipment, and hydraulic cylinders.

Order part number U90346, sold individually. Nominal inside diameter is listed as 4 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
