Gas Cylinders & Exchanges

CO2 and Nitrogen Tank Exchanges for Draft Beverage Systems

Gas cylinders and exchanges keep draft beer, sparkling water, cold brew, and other beverage systems pressurized and pouring correctly. Use this collection for CO2 and nitrogen tank exchange options, replacement cylinders, and gas-service products that support kegerators, home bars, keezer builds, and small draft setups.

Choose the cylinder around your draft system, available space, refill or exchange plan, regulator connection, and beverage style. CO2 is the standard choice for most beer, cider, soda, and sparkling beverages. Nitrogen or beer gas is used for specific draft applications that call for a different gas blend or serving character.

Planning your draft gas setup

• CO2 service: common for carbonating and serving most homebrew beer, cider, soda, sparkling water, and kegged beverages.
• Nitrogen service: used for specific draft systems, stout-style service, cold brew setups, or products designed for nitrogen pressure.
• Regulator fit: match the gas cylinder to a compatible regulator, tubing, disconnects, and keg hardware.
• Local exchange planning: check product details and availability before planning a same-day gas exchange.

For the rest of the draft path, browse regulators, keg tubing and hardware, kegging equipment, or start with a common 5 lb CO2 tank exchange.
