Build out your custom draft system exactly the way you want with the Coldbreak 4-Foot Blue Air Line (SKU: BLUEAIR4). We specifically use bright blue tubing for our gas lines to ensure you can instantly differentiate them from your beverage lines in a crowded kegerator or jockey box.
Unlike pre-assembled lines, this 4-foot section comes with both ends completely open. This open-ended design gives you the ultimate flexibility to attach your own specific hardware, making it easy to connect one end to a gas manifold and the other to the beer coupler of your choice—whether that is a standard Sanke D, a ball lock disconnect, or any other fitting. Featuring a standard 5/16″ Inside Diameter (ID) and 9/16″ Outside Diameter (OD), it provides the perfect foundation for a reliable, customized CO2 setup.
