Hi guys,

I'm not sure how to describe this, but here goes.

I'm just in the process of trying to setup my gas supply. I have a gas manifold to go to my taps, so for my bar setup the gas will go from the reg to the manifold. However, I would also like to use the same reg on a party setup, in which the gasline goes from the reg to the keg.

Problem is I don't like doing and undoing hose clamps etc to connect/disconnect it. I want something easy, shiney and cute!

I have in my mind some kind of inline gas quick release, based on the same principle as a airgun hose. I am sure they exist - but I can't find any mention of them on AHB using the search or on the web. I'm sure I just don't know the term for it - it seems that "inline gas quick and easy shiny release thingy that is also cute" doesn't help me find it either!

Any suggestions? product name would be good, where I can get one would be better, and one delivered to my house tomorrow by 9 would be best ;)

:beer:

Do you mean something like this from morebeer ?
So you would have the female side before your gas manifold, and another connected to your party gas disconnect.
Then one male side permanently connect to your reg.

Probably, but it would be a lot more expensive :lol:

LOL - thats normally the case. And I won't see it often, so probably can cope with off white :D

Thanks again, its just what I'm after.

Those disconnects are made by a company called Colder, you can get them from Vicfit in melbourne, but they are a bit pricy.

i saw some compressed air type quick connects at bunnings. there were about 4 different types. not sure what the differences are & if they suitable for co2. of course bunnings had a relatively incomplete stock range & no one there was especially knowledgable, so probaly pay to check out a specialist type shop, maybe gasweld ?

I considered all kinds of disconnects, but in the end went with some simple John Guest fittings. Cost be about $2, work perfectly.

In Matts case he would need to disconnect the gas lines from the kegs though using the John Guest fittings, because as soon as he disconnected the line the gas would escape from each keg.
The Colder fittings have shut off valves in them.

Although, the manifold does have an on/off valve at each port, so I could just turn all the gas lines off there - four levers.

How easy are the john guest fittings to disconnect? I think they are the sort on my flow reducers (a smooth grey fitting that just slides into a holder and looks like it will never stay in there!), and after putting one in I did have to swear, hold my tongue just right, stand on one leg and squint before I could get the damn thing out!

If you just jammed the line into the flow restrictor then it will be hard to remove.
I got the associated male stem side that makes it really easy to remove. Push in a little, hold the other side and it comes straight out.
I'll try and find a pic I posted here a while back of the assoicated stem for the flow restrictor.

Righto, I've been investigating it a bit more - And after saying to myself "what I'd really like is a gas disconnect the same as the keg" it dawned on me - why don't I just do that.

so I have just pulled apart the manifold, and the threaded section is a tapered thread of some sort - no doubt it will be able to be matched. I happen to have a couple of spare posts for my kegs, so sat them all together - I can't see why I can't do this. All I have to do is find (or more likely get made) an adapter to go from the male thread of the manifold to the male thread of the post.

Heres a photo showing it....

The theory is then I have a regulator to gas disconnect line, and it hooks up to the manifold. To switch it to the party keg, I just unhook the disconnect and hook it up to the party keg!

Am a crazy? Or could this just about work?

Photo of the manifold and post attached - I got the manifold from BD.
Just for kicks I'll also attach my party keg cooler - I found the snaplock fitting I bought for my font is a PERFECT fit for the hole when the tap is removed! Its fate!

I have been wondering about using the disconnects for air compressors for this type of thing as you can get them quite cheap at Bunnings or SuperCheap Auto. Any thoughts from anyone.

I'd be a bit cautious about the cheap disconnects, I've found they tend to have small leaks. No real problem when you're using a compressor (more annoying), but you don't want to run out of CO2 because of a small leak.

I ran around a few hosing places today and didn't come up with much. They couldn't match the thread of the post from a keg, so using a standard QD was ruled out. Then they found some inline gas disconnects, but at $45, I wasn't interested!

In the end I went to Andale to pick up some other stuff - the guy there reccomended the John Guest fittings, and showed me how they worked. There is even a cool tool for removing the stems, which he couldn't provide, but said I should be able to buy or make.

In the end I walked out with the John guest fittings - and because I've been there so much latley, he charged me for the male stems, but gave me the female:female adapter for free - $9 later, and I have my solution!
