568-434 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90434, an AS568-434 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.15 in (156.21 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and long wear life in dynamic reciprocating service. The material holds up against extrusion under high pressure, ozone, and impact and shock loading. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or prolonged humidity at elevated temperature.

Common environments for this compound include construction machinery, mining and heavy equipment, and high-pressure fluid power.

Reference part number U90434 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
