Does anyone have any good ideas for a setup that would allow for an easy way to remove my keezer Co2 tank and use it for other purposes like my beer gun or for a co2 pressure carboy siphon transfer?
I was thinking of installing a quick disconnect on the main Co2 line for my keezer, but I guess I’d worry about an air leak with the connection.
What do you all do?
And yes I know the simplest solution would be to just get another tank
Kent disconnects are great and cheap. You can also find more expensive disconnects that include auto shutoff.
I have a Kent connector on both of my regulators. I attach accessories and extension lines for the task at hand.

Edit - one thing to note is you will need to soften the tuning with very hot water to get it on the 3/8" barb.
I wrote this article a 2.5 years ago. I still have the same quick disconnects installed exactly as shown in the article. They’re great. No leaks so far. 
I use regular old quick disconnects, like you would for any pneumatic tools.
I recall a keezer thread where somebody had hooked up a QD of some sort where the line went into the keezer. I don’t recall who or how.
You’ll need something that shuts off the line on each side of the QD. The ones I use only close on one side, so if I left the gas line hooked to the keg it would vent out.
I used an MFL-to-MFL bulkhead to install a CO2 post on my brewing refrigerator.

Not a bad solution compared to a brass nipple and barbs.
I NEED one of those!
Does the ball lock post attach directly to the MFL, or is there some adaptation?
Nice, Mark. I like it. I’ve always run CO2 lines through a couple tight fitting rubber grommets into a manifold on the inside of the unit, but I like the looks of that.
Edited for brain fart.
Now, if I can just find a gas manifold that does not have a leaky shutoff valve, I will be golden. The first manifold that I installed did not leak, but it had a faulty check valve that resulted in back flow when I connected a pressurized keg that was filled to slightly above the gas line tube to the distribution system when it was not pressurized. I have since purchased two manifolds that have had leaky valves. I test all of my gas fittings with soapy water.
My MoreBeer brass manifold works well and doesn’t leak when in the open or closed positions. It does give of a slight hiss between open and closed, but when it comes to gas there isn’t a point in opening the valve part way. It did have a stuck check valve, but I was able to unstick it with high pressure.
By the way, the setup is an assembly that consists of the following parts:
1/4" MFL-to-MFL bulkhead
1/4" FFL-to-Cornelius Post (19/32"-18) adapter
1/4" flare swivel to 1/4" barb fitting
Cornelius (19/32"-18) ball-lock gas post
nice, I will be doing this in the next few days, thank you!!!
You need to get pneumatic fittings like the ones the pubs use. John Guest is a popular brand:
