Add a CO2 distributor to your system to supply gas to multiple kegs with one regulator. Corrosion-resistant nickel-plated brass manifold has 1/4" MFL shut-off valves with an integral check valve to prevent backflow of gas or liquid. Requires barbed swivel nuts (#K123 or K163) to connect hoses. We recommend using a flared nylon washer (#K127) and/or teflon tape at each connection to prevent leaks.
