Really? So, by regular ring.. you mean the one that goes between the tube and the keg? There doesn't seem to be anything to contain it. Thought I'd try to stack a couple of O-Rings.. I can't picture an 0-ring fat enough to do that job.. I'm also going to check McMaster.. I know there is such a thing as a square cross section O Ring. I think I can get by with what I have now.. but for the future.. I ought to pick up a few...
