I was cleaning my Ody and dropped the small o-ring at the end of the rebuildable part, the one that goes on end of unit near 510 post. I pulled one out of the ones that came with it when I got it. I think I might have used the wrond size. SInce then Ive been have a minor seepage of juice and I notice I get slight hard draw and less vapour after a while. I think it might be because of wrong o-ring. If you could help me identify which one is the correct one Id appreciate it. The one on my rebuildable part is another one that looks like the smaller one shown. It might be another 0-ring for some other part.
