My favorite drip tip has a busted o ring and the other one on it is not fairing so well either. It is one from Suicide Bunny and i have taken some orings off other drip tips and they did not work out so well. I am also a big erkronogin used and those two small o rings on the top disappear very fast. I know those are 3x1 but that does not tell me in ID. Does anyone have a good place to get replacement Orings at? I have looked all over the place and since i am not really sure what i am getting i dont want to have a million orings around. Now i did find an oring set on ebay for about 13 and was thinking about picking that up. It says it has the 3x1 in there.
