Default Does CO2 go bad?

I picked up some used corny kegs and and friend of mine gave me a CO2 tank along with gauges. Now I don't know how old the CO2 is, it can be between 1 - 15 years old.

So before I swap the tank (only to refill around here) could I simple use the CO2 I have?

CO2 only goes bad when it's missing an Oxygen ion.

CO2 will stay CO2 so you should be fine.

guys, I'm sure that inert gas STAYS pretty inert, but what about rust or corrosion inside the tank?
15 yrs?

I'd say it's probably fine, but I do know the tanks are supposed to be inspected every so many years. I think it was every 5 years.

OP, you're fine. Use what's left inside the tank, and do a fill/exchange when you're out of gas. The tank will be out of it's hydro cert, so they won't be able to refill it w/out doing the testing process for a nominal fee. Unless it's really corroded, it should pass without issue.

Yep, CO2 tanks need to be hydro tested every 5 years. On the tank there should be a two number date MM/YY. The tank needs to be tested 5 years from that date.

being fine or not. I think your problem will come when the tank is empty. Refilling or exchanging it might be a problem.

I think it was 10 years and they won't refill or Exchange it. I think you can get it inspected. My first tank was older. Pefrect shape though. The guy exchanged it no problem. So you may be n luck.

Try a welding supply place if your LHBS shoots you down.
