Beer Line Tubing Info


  • Hello,

    I wanted to know, what is the size of the clear beer line tubing used for dispensing from the keg? Is is 3/16" inside diamter or something else? Do i need a certain outside diameter as well, in order for it to fit into the pour spout properly, or is the standard 3/16" tubing correct?

    If I wanted to replace the tubing that came on the keg with a longer run, is it as simple as pulling it off of the black nozzle peice and pushing a length of new tubing on, or is there anything special I need to do?

    Thank you for your help



  • I'd be interested in seeing how this works. A longer beer suply line might solve the foam problem.


  • That was my thought as well. The ~1' section of line seems way too short to provide a propoer resistence, especially at 15 psi, which is what my machine seems to be set to by default, and I haven't found a way to change that yet.

    I recieved the master mode card, so hoping that unlocks something to let me choose my own psi, but need to wait until my current batch is done fermenting before i can use it.


  • Hi Ryan, I will find out and let you know asap.


  • @Ryan The outer diameter is 7mm, the inner diameter is 4mm, and the length is 270mm


  • @April  Thank you for those specs! Would you be able to tell me the material as well? Silicone, Vinyl, PVC, or something else?


  • @Ryan did you ever hear back?  I too would like to know the material as I had a line burst during fermentation and it blew the whole batch all over the machine and the bar top. What a mess. Luckily there was a second line in the kit but not sure what to replace it with after the second fails. @April Hsiung any suggestions?


  • @Ted I didn't hear back on the material, but determined they are using silicone tubing. I was having some trouble finding their size of 7mm OD and 4mm ID readily available. I did a bunch of trial and error on some other different size pipes, and found that 1/8" ID and 1/4" OD diameter works best for me.

    This is what I wound up using. I went with a 9 to 10' long peice, and it seems to provide good pours for whatever pressures the system uses. Getting below 8' long I started seeing a little more foam than I prefer.
