Have you ever pulled the cover off the detent and moved the valve's spool; DON'T. Balls explode in midair. I needed a 11mm and a couple of 5.5mm. If you lose the spring, good luck. Of course, you have a bad O-ring too. If you have an older US made Energy valve, it is probably SAE. I might have used stainless if I found a kit with 11mm.

Needed just 3 to repair a 1940’s Japanese bicycle cart. But found the ones that where the same size. Cart is on the road again

It works and we'll label

This is a nice set of ball bearings. Used for a 3d printed project.
