Maintenance and OEM teams specify it across construction machinery, high-pressure fluid power, and off-highway equipment.

This item is sold individually under part number U90433. Nominal inside diameter is listed as 5 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
