The 4-Way Splitter CO2 Beer Gas Manifold/Distributor is a crucial piece of equipment for home brew enthusiasts. Made from durable aluminium, this product allows for efficient dispensing of beer with the help of 1/4" shutoff valves and a regulator. Originating from China, this beer dispensing equipment ensures a smooth and controlled pouring experience, making it a valuable addition to any home bar or brewing setup. This is used and works fine, I've just gone for a 6 way and this is now unwanted. both the connections in and out are ¼" FFL and the non return valve is still working fine as I've literally just checked it.
