Question: What Does Ounce Refer to with a CO2 Tank?
Answer: Carbon Dioxide (CO2) tanks typically come in 9-, 12-, 16-, and 20-ounce varieties. These numbers refer to how many weight ounces of liquid CO2 can fit in the tank. When you fill a CO2 tank be sure that only the specified weight is added to the tank to avoid risk of over filling, drain the tank of any remaining CO2 before refilling. Overfilling can result in blowing out the safety burst disk, rendering the tank unusable until the burst disk is replaced.
