Extending draft beer lines
Typically the easiest way to do this is with a reducing splice, hose clamp, and larger diameter tubing. 3/8" diameter tubing
is the most common material to splice into to extend your lines 5-10’, which will allow you to maintain a proper flow rate. Keep in mind that you need to keep all parts of the beer lines cold, even if it is just a few feet, to prevent issues with foamy beer.
