Pipe Thread Tape between Regulator and CO2 Tank?

So I isolated one of the leaks (between the regulator itself and the tube that connects the regulator to the CO2 tank), went through spraying down the rest of the connections and for the most part everything seems ok.

I'm seeing a very small amount of bubbles on the output of the CO2 tank, where it connects to the tube I mentioned above. I haven't been in the habit of putting that white pipe thread tape on the CO2 tank threads (it's on all the other threads in the system though). Do people do this usually?
 
If you're talking about the connection from the whole regulator setup to the tank, then no, you should not have to put teflon tape on those threads. If there is a gasket seal between them, it may be worn out or damaged, or if there is no gasket then there may be a nick in the parts that join and make the seal.
 
There is a gasket seal, which is working fine. I'm not talking about the side of the nut that the regulator is on, I'm talking about the side that the tank is one. So, what i mean is, on the actual threads of the CO2 tank, where it threads into the nut that connects the CO2 tank to the regulator, that's where I'm seeing some bubbles.
 
What you are describing is the exact connection that should not need additional antileaking material. Tighten the nut tighter, check your seal, this should not leak. It is the most frequent area of escape, and it will drain your CO2 tank quickly. If done right then your tank should last for months. But to reiterate, There should not be any tape at this connection. Good luck.
 
well that's disconcerting. i absolutely cannot tighten it any more. hrm
 
Pacpac is right, that's exactly the connection I was referring to. Some CO2 setups have a gasket in this connection. I know this because I have a small bottle on the car in my avatar, and it has a gasket seal at the bottle. So if there is a teflon or similar type gasket there, try getting a new one.
