Does the gas bottle need to be attached all the time, or can i use one bottle to gas a few kegs

Many Thanks

I have recently started using Corny kegs.

I keep 2 kegs in a fridge, the gas comes from a single cylinder and the gas lines are separated with a "Y" piece and each line has an isolation valve.

I don't leave the cylinder switched on all the time, I will set the pressure for force carbonation or for serving as required, open or close off the appropriate keg, then give a blast to the required cylinder. I then turn off the gas supply to avoid losses due to leaks.

Works for me.

can i use one bottle to gas a few kegs

This is what I'm doing. Like gobuchul I have two in the fridge but I also do 40 litre brew days sometimes (2 kegs plus a couple of PET bottles for the excess). A simple Y splitter wouldn't help. I couldn't carbonate two kegs over a few days at 20PSI room temperature and also keep gas on the two in the fridge at 10PSI. I just switch the one gas line as needed.

My thinking was that cornies are designed to have a much rougher life than we give them and quality disconnects (e.g. CMB from the Malt Miller) must be the same, therefore they should handle being connected up to a keg hundreds/thousands of times?

I've tested with soapy water and don't think I have any leaks but I keep the gas turned off if I remember.

+1 for CMB disconnects. Others are cheap, inferior imitations that promote anger with a claw hammer. It's fine to keep the gas on, but lube the seals and triple check for leaks. I tend to prime kegs these days. I force carb if I'm in a hurry. If you want to force carb, you could use a carbonation lid. They are very effective. A dual regulator is very useful to have too, you could be force carbing and serving at the same time from one CO2 cylinder.

So what else would i need to buy apart from the Keg's, i have a c02 vessel that i use to charge an Air rifle

lube the seals.

Yes, I bought food grade lubricant and use a tiny bit on a post/disco every few weeks.

[McMullan]

For a basic set up: keg lube (K-Y jelly will do the same job), 2 CMB disconnects (1 gas in, 1 liquid out), length of gas hose (flexible is better), tap for dispensing, regulator and I'd probably get a beverage grade CO2 cylinder that holds 2-4kg of gas. There are lots of suppliers, some good, some not. Post back before committing to buying anything.

so bit of a thread hijack but in a similar situation, i've got a regulator a jg fitting for it and a jg fitting for the gas in post. http://www.ebay.co.uk/itm/271764985235? ... EBIDX%3AIT

only thing is the thread on the gas disconect jg fitting is far to short for me to be able to screw it onto my disconect and the i have some 3/8 od gas line http://www.ebay.co.uk/itm/221308449071? ... EBIDX%3AIT but there is no way it's ever fitting n the jg push fits. what have i done wrong and is this sittuation salviagble of should i just go down barbed fittings.

final question can anyone link me to the parts i need to use 3/16 beerline with jg fittings including which is the easiest beer out ball lock disconnect to purchase.

Have a look at this web page. You can see the JG part numbers for example.

When I was doing my final build, I didn't even bother trying the short 3/8 line party tap. I got a few metres of "3/16 beer line" and two "3/8 to 3/16 reducing straight connectors" from stonehelm.co.uk. I snipped the party tap beer line a few cm from each end and connected in five feet of 3/16.

yep i used maltmiller to get an idea of parts. i just can't see how to get 3/8 od line into a jg fitting. my 7/16 TO 3/8 ADAPTER is the same also but the thread section on the disconnect is to long for it to attach. disconnect looks like this

[McMullan]

There are a number of options here

My preference for the CO2 side is a hose barb (screwed onto the disconnect) and flexible CO2 hose (the rigid line is, well rigid and fine if you have a fixed set up).

3/8 beer line has 0.25 inch ID which is nearer 6mm, that braided hose is 5mm ID, is the hose wall a bit too thick?

I have one or two mm of thread showing when the JG fitting is tightened on the grey disconnect.

This was an example of the hose. You can get it with different ID (down to 4mm) and get compatible barbs (brewferm) that will fit the disconnect.

Should have said, I like JG fittings, but not on the CO2 side. I find it much better with flexible hose. It's easier to move it around from keg to keg and take it travelling, etc. The rigid tubes aren't really designed for that.
