Dangerous Leak problem

Your powertube has nothing to do with leaks. You can have your powertube off and have just the valve secured in the gun and it will not leak. The powertube simply houses and directs the valve.

As for your problem, its most likely a very small leak, caused by a minor mis-seal in your valve. But my guess is it is coming from stainless steel (SS) line where it screws into your valve.

So the first thing you should do is drop 3 drops of oil into your ASA (tank adapter). Then dryfire (just air) 30 shots without the barrel to get it circulated and get the extra out. This will make everything seal up better in your valve. If this doesnt solve it, unscrew your SS line, and re-seal the threads with teflon tape.

Loctite may be a little easier to use. But Teflon Tape or Plumbers Tape is a much better sealent, but its a little harder to use. To use it properly do it here- http://model98.net/tts2.html 

I was wondering.  My A-5 seems to be having some problems.  It seems that liquid CO2 is getting in the trigger.  I was just shooting and it seemed that the whole trigger was getting cold.  Then when i looked i saw that the WHOLE trigger line had frost on the skin of the gun.  Now, this obviously seems like a tank problem, but this is the second tank i have had on it and it is STILL freezing.  PLEASE HELP!

^ This isnt really a problem as much as an occurance. This happens when you suck up and fire liquid co2, or actualy every time you shoot. The gas used to blow back the bolt finds anywhere (including the trigger frame) to vent out air, but its easier to see when you get some liquid. When you suck up liquid co2, it condenses and "freezes up" everywhere its used, and you can see a white cloud.

Try to keep your gun not pointed down when you shoot so you dont suck any up.

brn 5-0 where did you get your replacement power tube
