I spent some time with this ring. If you don't care to read this whole post the short of it is the IBTpro is made for IBTanked tanks.
Too obvious sounding? OK, then you'll have to read on.
I wrote in an earlier post that this ring is tall. Here are some quick and dirty measurements.
Rings height measurements in mm from shortest to tallest.
Taroe ring SS | 5.62 |
Bombvapor Pro Ring | 5.91 |
Tatroe ring Brass | 6.05 |
Kayfun PV cone | 6.33 |
Loki Machined(older) | 6.35 |
Loki Polished | 6.43 |
Loki Machined(newer) | 6.44 |
Loki Black Delrin | 6.46 |
KirFanis ring type 2 | 6.56 |
IBT Pro Ring | 8.25 |
In the shortest to tallest order. You can really see how much taller this ring is compared to the rest.
The IBTpro looks great on IBTanked tanks. The taper is perfect from the ProVari to the tank caps. The concave top matches the bevel of the caps so it and gives the most flush, gapless look possible. The extra height also solves the carto length problem with IBTanked tanks. Using other rings(or no ring at all) the cartos stick out of the top of the IBTanked tanks a few mm. You can see in the pics below that with the IBTpro the cartos are now flush with the top of the tank and with the other rings the carto sticks out a bit.

So it works perfect with the IBTanked tanks. What about other tanks? Well it works with the Phiniac but it looks terrible because of the 23.85mm caps. No issues with cartos fitting.
Here it is with the Loki SS1 and the GP SnP 22mm. It doesn't look bad but now we have some problems. The carto punches are now in the bottom cap. The top of the carto is well below the top of the tank. In the SnP you can see the o-ring. It has 2 so not really a problem.

So it works best with only the IBTanked tanks. What about Attys? I cannot get either the Kayfun or Ithaka to reach the 510 connector. Neither will screw down at all with the IBTpro. I imagine it would be the same for just about any other 22-23mm atty.
So the IBTpro, when matched with IBTanked tanks, is a GREAT ring that gives a great look. If you're not using IBTanked tanks exclusively, it won't be your only ring. You'll just have to buy them all like me
Hope this helps!
