H1 12 Bolt Valve Stem Oring Size?

[adamk]

Does anyone know the size of the valve stem oring that is used on 12 bolt wheels? TWF sells them but I'm not going to pay $5 each when I can get one of my vendors at work to supply them for much much less. I just need to know the size but do not have one to measure from.

Thanks,
Adam

About all the ones I saw for sale are just buna-N, so you can get 100 pack for a few bucks if you can find the size.

I found them for a buck a piece and will just have to go that route. I was able to locate one and take some measurements from it but I believe the one I measured had swelled some because I was unable to find a size close to it.
