View model pageGeneral guidance
In general, a ball in a hydraulic or fluid control assembly is a small precision sphere that works with a seat to open or close a flow path, acting as a check or shut-off element. Exact dimensions, material and the surrounding hardware must be confirmed against the catalog entry for this part number.
Order using part number 0066803 exactly as listed. Before ordering, confirm that the catalog associations and any recorded serial or configuration conditions match your machine, since a catalog listing does not establish compatibility for every configuration.
