SO I ordered some stuff in anticipation of my kayfun 3.1s arrival, mostly spare O rings, plastic tanks etc. I also ordered a Kayfun Provari flush ring, I couldn't remember if they came with one or not. Anyways it was 8 bucks from vape rev. I just tried it on, nice is all I can say, probebly the tightest fitting ring I have tried to date, unlike a few other rings I have tried, it fits so tight it will shut the air off completely.
The first pick is of the Kayfun ring and a 22mm IBT, there is a very slight taper to it, maybe to better match the diameter of the Kayfun? I don't know, I'll check tomorrow if it's here. The second pic is of the hippo with the same tank.


In both picks, the tank is down as low as it will go. I think a realy clean look if you needed airflow would be to just drill a 1/16 hole in the kayfun ring. For 8 clams I don't think you can go wrong. As far as I can tell the Kayfun ring is SS. I still prefer the hippo ring, it's adjustable, protects the threads of your provaris 510 connecter and you can use it with any diameter device because it threads into your Provari's 510 connecter and doesn't rely on your tank to stay on. If your looking for a flush ring the kayfun is defiantly well worth a look, defiantly well worth 8 dollars.
