568-909 URETHANE 90 ORINGS -PREM GRADE

The U90909 is an AS568-909 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 0.706 in (17.93 mm), a cross section of 0.097 in (2.46 mm), and an outside diameter of 0.9 in (22.86 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and long wear life in dynamic reciprocating service. It resists abrasion and wear, petroleum oils, and ozone. Continuous operating temperature is published at -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.

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

Order part number U90909, sold individually. Nominal inside diameter is listed as 9/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
