I lost that one. It either went in the trash, or down the drain. It is TINY. I ordered from two places, trying to find an o ring to fit. The smallest was 1mm x1mm. It was still too big. I saw Apple Rubber has small micro sized o rings. I sent them an email, and they never even responded to me. That was on the 10th, still no answer. Does anyone happen to know the size of that o ring, and where to get them? I have the Kayfun 3.1 ES, and it is a clone. I wanted food grade if possible in o rings too. I guess what I was interested in, wasn't worth their trouble. I would buy a small pack of them, if I can find them that is. I don't have calipers, but even if I did, I don't have the original o ring to measure. Any help would be greatly appreciated.
Oh, this is the e liquid duct o ring, on the top of the deck base. (in case you don't have a diagram)
