Actually the pressure is more around 600-900psi. I just googled it and several sources stated this. The pressure varies because of temperature.

So in one temperature, is the pressure in the tanks exactly the same?

A 1/2" chamber that is 6" long will probably reach 500-700psi if you filled it with a 12g and you would probably not live to be able to tell us what happened.

attully more like 300psi 1/2" pipe is rated pretty high so it might not burst but isn't at all safe

co2 liqufies at about 800 psi depending on the temp, so untill the chamber over flows with liquid co2 it will not rais the psi and vis versa the psi will not drop untill the liquid co2 is depleted, same with propane, thats why if youve ever shaken a can of propane or co2 it feels liquidy

according to that a 1/2 by 6 inch chamber would be about 840 psi, assuming it was possible to empty the entire cartridge into it also it would be 800 psi with small amount of liquid co2

I can barley read your message, dude. I don't mean to offend you, but your grammar, punctuation, and sentence structure are pretty much illegible. Is English your second language?

If you'll rephrase your question, we can try to help you.
The spell-checker will help you a lot. You can also try writing your message in a word processing program and then copy-and-pasting it to the forum.

Peace,

Sorry dude, i just wake up.. (not excuse -_-)
yes, English is my second language.

what i try to say is that i don't know how to connect the CO2 soda-stream tank to steel chamber without to take the soda-stream machine connectoin.
i can't use any connection that in the fix measure because there is wired opening to the tank

and CO2 C-A-N N-O-T be liquid because CO2 molecules can't be to other CO2 molecule in way that they will be liquid, this is the model of the molecule, CO2 can be just gas or solid
