Brand new aluminum 20 lb CO2 tank made from high strength aluminum alloy and high quality CGA320 valves. Because it is made of aluminum rather than steel you can feel confident that it won’t rust. It’s called a 20 lb tank because it holds 20 lbs of compressed (liquified) CO2. 20 lbs of CO2 is enough to dispense about 40x 5-gallon kegs of homebrew.
Aluminum tanks are superior to steel because they do not rust. All tanks are shipped empty. To have tanks filled you will want to visit your local welding supply shop. Because you are purchasing a new tank you can choose to either have it filled or to exchange it for a filled tank at your local gas supplier. If you have this tank filled the local gas supplier is responsible for affixing the correct neck label that identifies the gas being put in the cylinder.
Tanks should always be stored in an upright position.
