Rex, Thanks for the info. Do you know where I can get one of those permanent brass seals for the tank/regulator? All is working fine now, so I'll not mess with it for the time being, but whenever i have to change the tank, I'd like to have one of those, sounds like the ideal solution.

I'm going to take my CO2 tank out and weigh it tonight. That's the only true way I'll know if I have a leak or not. Otherwise pressure is stable at 820psi right now and everything seems to be working fine. I took a big cup of water and submerged my entire needle valve to regulator union and didn't see any bubbles forming on the valve, regulator or the vinyl tubing. When I put the tank back, after weighing, I'm going to tighten the regulator to tank connection a bit more. That nylon washer probably sees some plastic creep after a while and probably needs occasional re-tightening until it settles.

I got the brass seal from the fire extinguisher place that fills my tank. I'll bet if you ask at a welding shop they might carry them also.

I know the problem Sam... you have too many dang connections !

Here is my setup...
Bottle to the Regulator to the Needle Valve to the "Air" Tubing Into The Tank

Reactor - Filstar XP2
Bubble Counter - That's me! I watch the intake tube of my filter suck up the bubble... 1 every 3-4 seconds

All the CO2 ya need without the Science Project...yeh im lazy
