Hey everyone so about 2 months ago I picked up a Kanger Sub-tank Plus and loved it. However about a week or so after I picked it up, the bottom seal started to leak. Frustrated with the wasted juice and mess it created I ran out to my LVS, and picked up a new pack of seals, this worked for another week or so however the problem persisted. After another week or so of wrapping my tank with paper towel, I set out to find a solution. Long story short nothing was working until I used Teflon tape. I used a strip about 3" long, taped both ends down and used a razor knife to cut roughly a 1/3 of the strip off length wise. Wrap it around the threads of the bottom piece of the tank make sure you wrap it clockwise so that it doesn't unwrap when you screw the tank back together, and try not to overlap it because it wont tighten down correctly with out a lot of force and you could end up cracking the glass, or damaging the threads. Once all this is done screw it back together fill it with your favorite juice and enjoy. I haven't had any issues with leaking since, I know its a bit of a hassle to do every time but between the money lost from wasted juice and the constant mess I was cleaning up I feel it's worth it. I hope this helps some people out take care and vape on.
