I don't have any measurements, but the clear OMG o-rings from HoH on this Kabuki are the loosest rings I have (I have other OMG o-rings but haven't used them yet). Take the bottom off and the glass practically falls off the top piece. Thing is, ALL the o-rings work on my Kabukis ... buna, silicone, OMG ... and none leak. Also, I seem to always have to use a tank wrench regardless. Prolly because I have little concern for over tightening since the wrench works great. My point I guess, based on my limited experience ... the OMG rings MAY ... MIGHT ... COULD BE a different size somehow than the standard black buna and silicone. Thoughts?
EDIT: Only time I've EVER had a Kabuki o-ring issue was when the tanks were brand spanking new and a little difficult to get apart without damage to o-ring or sleeve. After some use, one tank of juice, all o-rings work fine.
