CO2 Tank Used as a Beer Gas (N02) Tank, Conversion?

[OneHotKarl]

Hey everyone, I have a question. I have an extra 5 pound C02 tank laying around and i was wondering if I could convert it for beer gas use? From what I read on the micromatic web page the 'dip tube' goes down 3/4 of the way to get a proper mixture of gas. Could I modify the dip tube of the co2 tank after having the valve removed from the tank? Or are the threads different? Also is the tank hydro-tested for co2 only?

Thanks.

It might not be necessary.

My local fire extinguisher store fills reg CO2 tanks with either CO2 or beer gas...no mods needed

Davidson Fire Extinguishers, Its a little shop in Ottawa, Ontario. Ive gotten beer gas and straight CO2 from them in the same tank at different times of course.

I thought that beer gas was dispensed from nitrogen tanks, and those tanks are rated for a higher pressure than C02 tanks.

I get my CO2 from a welding supply shop, and I asked about beergas. He said he does not stock it, but he can get it so just call ahead a few days early for the exchange.
