Building 3 keg system. Parts List

[jackle]

In my freezer (that currently has 1 keg) I plan to have 3 kegs. 1/2 keg, 1/4 keg and a corny keg for some homebrew. Here is what I what I "think" I need. I am wondering if there is any special parts because I dont know about the corny kegs.


(1) Dual guage co2 regulator with dual keg output
(1) C02 regulator splitter
(2) D-Couplers
(3) C02 lines (what kind for corny keg?)
(1) Cornelius Keg
(1) 15 lb C02 bottle
(3) Beer towers
(3) Beer lines (again, what kind for corny?)
(1?) Corny keg coupler (No idea?)

I guess what I am askikng for is an explanation of the corny keg. I just purchased a refurbished "ball lock" corny from ebay. Is this the right type of keg? The add also mentioned pin locks, what is the difference?

Also, on the regulator. My dual keg regulator will have to be split so that one of the c02 valves goes to 2 kegs. Are the co2 diameters for corny couplers different than that of my regulator?

Please advise if this configuration will work. I appreciate it!
