Part number U70241 is an AS568-241 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 3.859 in (98.02 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.137 in (105.08 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service and exceptional abrasion resistance. The material holds up against impact and shock loading, petroleum oils, and ozone. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving hot water and steam or ketones call for a different compound.
Maintenance and OEM teams specify it across off-highway equipment, high-pressure fluid power, and hydraulic cylinders.
Stocked as U70241 and sold individually. Nominal inside diameter is listed as 3 7/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
