Product Specification

-
Ordered as U90431, this is an AS568-431 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 5.225 in (132.72 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.775 in (146.69 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service and exceptional abrasion resistance. The material holds up against ozone, impact and shock loading, and petroleum oils. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with ketones or acids and bases.

Maintenance and OEM teams specify it across mining and heavy equipment, press and forming equipment, and hydraulic cylinders.

Stocked as U90431 and sold individually. Nominal inside diameter is listed as 5 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
