I know that most people have a huge problem with the lack of air flow when you tighten down a Protank flush to a Provari. It even states it on the Provape site that the Protank should not be tightened all the way down due to airflow issues.
From Provape...
NOTE: Due to the design of the new ProTank 2 we recommend that you don't screw the tank down all the way to the ProVari. This will reduce the airflow. For best results, screw the tank on just to the point where you start to feel it tighten but don't turn it any further. It will still have a secure connection to the ProVari and allow for proper airflow.
This is the remedy to have a nicely flush Protank without cutting off air flow or over tightening. Takes 1 minute.
1. Get any decent sand paper (I used 400 grit) and slowly roll the base of the coil unit back and forth to remove a SMALL amount of material from the bottom. Make sure not to get metal up the hole or remove too much material. I would take maybe 10 swipes back and forth and test the fitment and air draw before removing more material.


2. Screw onto the base.

3. Attach to the Provari

You will notice that it take very little pressure to get the tank tightened all the way down. The draw will be a very nice draw, good for both mouth and lung hits. I know this was way too easy and I hope this will work the same for you guys.
