Co2 tank/line quick disconnect?
« on: December 23, 2015, 05:52:52 PM »
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

You need to get pneumatic fittings like the ones the pubs use. John Guest is a popular brand:
