I'm thinking of buying this kegerator on Amazon, but was wondering if the smaller tank size will make it harder to find a place to fill it. Also, if I'd like a bigger tank at some point will the regulator and tubes still work?

A CO2 regulator has a standard connector which would fit any size CO2 tank you'd be able to handle at the home level.

Most people start with a standard 5 lb tank. Its about 6 inches wide, and 1.5 feet tall. The next size up is a 20lb tank. Its something like 2 feet tall and 8 inches wide. Those are the most popular.

I strongly recommend finding a place that fills tanks before you buy a tank. Near me they only do exchanges. SO you pay a one time deposit on the tank, and then its $12 to swap said tank for each "refill".

If you do find a place that does refills, they'll have no problem filling any size tank, so I wouldn't worry about that.

  • Just a note - there are 10 lb tanks - I have one in my fridge now.

  • You know what, I meant to say 10lbs. I am home sick today so not thinking straight.

  • The "standard connector" for CO2 systems is CGA-320 (at least in the Americas), which apparently is used for CO2 and CH3F
