What size o ring is the power tube tip o ring, specifically?

[halB]

I have an emag valve where the power tube keeps coming loose in games.

I am getting some contradictory information. Some suggests that the power tube tip o ring is the same size as the other power tube o rings. Other comments, and the fact that AGD sells the power tube tip o rings separately, suggests that they are a different size than elsewhere on the valve. And nowhere do I find the actual size.

So, what is the actual size of those power tube tip o rings for an emag valve?

I can't give you the actual dimensions but it is a different size than the others.
