Recycled from a ford galaxy power steering rack this is the small one way valve that sits in the top of the steering rack inlet port .

Has a tendency to fall out when the rack is removed and drops out never to be found again.

19mm in diameter and 5mm width.

fits other steering racks made by ford to fit fiestas, focus, mondeo, s-maxs and c-maxs.

tried to find a part number but couldnt get into the catalog today.
