Yep, no problem.

CO2 tanks are CO2 tanks, no matter what they are used for.(this doesn't apply to paintball tanks).

Most sellers won't list this, but one thing to look at is it's connection, it should have a CGA-320 connection. But a cylinder listed for Beer/Soda will have this.

has the co2 tank you bought on e-bay been hydrostatically checked? all co2 tanks need to be checked and verified for safe use every 5 years (or 3... not sure).

5, some places will just swap it out, some places will charge you $20. Brand new cylinders should come with a hydro date on them. EDIT: well, actually, all cylinders will have the hydro date, but new ones should have a current hydro date.
