Dry the orings with paper napkin it will help. I asked imeo since mine too is a little loose but he assured me that after a few weeks it will settle in. Im going to look into using a different size oring to make it more resistant.For those who picked up a polished AD, how tight is your air control ring? Mine is very loose. If I hold the atomizer by the tank the ring will fall off the bottom. Right now I've got it on a mod where I can't quite flush mount it and the ring just drops down to until it hits the mod, leaving a gap between the ring and the bottom of the tank.
