Does anyone know the dimensions of the tubing/barbs/anything else I might need to hook up a standard CO2 tank to the ball-lock keg, then to a single tap draft tower?
I think it should be fairly simple to adapt to corny kegs (in fact there is a picture of the fridge filled with corny kegs.)
You have QDs for the kegs, so you have the connectors needed on the keg side. You also need hoses and connectors to connect the keg to the tower and to CO2:
- to beer in on the tower: push 6-10' of 3/16" beer line over the barbed beer out QD on the keg and clamp with a hose clamp. To connect the hose to the tower, use beer line connectors, like these. (You probably already have these on your existing beer out line.)
- CO2 from the tank. You connect the keg to the tank with 1/4" or 5/16" gas hose slipped over the gray gas QD and clamped. The regulator output is also barbed so you do the same with that - slip over the hose and clamp down.
And that's it!
If you have already the parts for the sanke (commercial) keg, but have no plans to use them, then you already have all the parts you need. You can then just cut off the keg coupler at the hose, and fix this to your beer QD, and do the same for the gas line.
