I was trying to make a keg party pump that was easily transportable, just a coupler, regulator and a paintball CO2 tank. The problem is that the paintball CO2 tank's threads are too small for the keg regulator I already have, does anyone know if there is someplace where I can get a conversion for this? I have a line from the CO2 tank with a quick release on it that looks like
So if anyone knows of a place to get that kind of quick release that would fit a standard keg regulator that would also be helpful.
Thanks

Can the regulator on this site be adjusted between 12 to 18 PSIG? If so, you could use these to regulate the appropriate pressure from your cylinder and possible adapt this to your pressure inlet on the coupler.

I don't actually have a paintball regulator, but I already have a regulator for a keg set up. So I was looking for a way to adapt the smaller paintball tank to make it fit the larger keg regulator.

I would recommend using a conventional cylinder for your regulator. They are designed to regulate high pressure.

I have a regular kegerator system set up with a regular size cylinder for it, but I wanted to make a transportable one so I wanted to use the smaller cylinder so I'd only have a small CO2 tank, regular and tap, then just a party style faucet, but the extra keg regulator I have is too large for the paintball CO2 tank.

If you can find an fitting that will adapt between the cylinder and the regulator, there should not be any issue as to dropping the internal pressure of your paintball cylinder to a usable pressure for the keg. Problem you will face is to find the fitting. What is the internal pressure of the paintball cylinder?

You can go to Williamsbrewing, they have the proper equipment to convert your regular regulator to a paintball tank regulator. in fact they sell paintball tank regulators pre-assembled.

I need to find the reverse... lol I need to convert this to a standard CO2 tank, I want to move to a 10# instead of paintball tanks.

I think it would be a good idea for anyone in this forum to buy one of those adapters. Since you never really know when you are going to run out of CO2, (or at least you don't get a lot of warning) it would be easy, and relatively cheap, to have a small paintball CO2 tank on hand in case of a beer emergency. It would at least get you through the night, or possible the weekend if your CO2 place is only open five days a week.

i was looking into the same thing.

not only do the threads not always fit but also a paintball co2 container had the pin that has to be pushed in which the regulator can't do. I found this which should do the trick ...

1/8 NPT ON/OFF Ball Valve [FITT016] - $16.00 : Palmers Pursuit Shop!, Where Custom Still Means Something
(you can also look for a "remote line fitting")

only thing i'm not sure about is if the male side is long enough to fit on the regulator and have a tight seal. If not then u will also have get a brass pipe adapter and a small piece of tubing.

i'll be able to let u all know more once i get mine finished and working

nobahdi · #11 (**permalink**) 05-29-2008, 11:19 AM

I forgot about that little pin which needs to be pressed. Be sure to post pictures when you get it working.

CoreyD · #12 (**permalink**) 05-29-2008, 04:50 PM

They make paintball tanks that have on/off valves with no pin.

um...you do know that CO2 tanks for paintball use liquid CO2 don't you........

CoreyD · #14 (**permalink**) 06-24-2008, 04:27 AM

All CO2 tanks use liquid.

Fastsc92 · #15 (**permalink**) 06-24-2008, 05:16 AM

But a paintball tank siphons it from the bottom...

digunderground · #16 (**permalink**) 06-25-2008, 06:31 AM

Actually all paintball tanks dont syphon they all pull from the headspace of the cilinder. This is exactly why you cant tip one over it will disperse liquid CO2 into your keg and possibly explode it. So if a paint ball tank syphoned from the bottom you would have to turn it upside down to ue it... which you dont.

I found another paintball tank adapter for your regulator. This one is even cooler, it can be used for either a paintball tank or a normal CO2 tank WITHOUT REMOVING THE ADAPTER!!

I use a paintball tank setup so if you have any questions please ask!!

How is it you can use this adapter for both a paintball tank and normal CO2 tank without removing the adapter?

CoreyD · #18 (**permalink**) 06-30-2008, 09:56 AM

Full size tanks and paintball tanks use the same thread. If you use a paintball tank with an on/off valve instead of the pin valve you can use a standard regulator. You just have to make sure that the threads on the regulator nut are long enough to catch the threads on the paintball tank valve.

digunderground · #19 (**permalink**) 07-01-2008, 06:17 AM

Actually the threads are the same, but the depths are not. The second one I posted from More Beer uses a pin to depress the paintball tank "valve" and that same pin doesnt interfere with the normal co2 tanks. ONLY THE ONE FROM MORE BEER WORKS ON BOTH!! Only this one has a detached tightening nut just like ones used for normal co2 tanks. The one from "Williams Brewing" ONLY works on paintball tanks.

The More Beer one works on both the pin actually fits in the small threaded hole in the center of the co2 tank connection, but doesnt block it or disrupt airflow.

Hope this all helps

If you get a paintball tank with the on/off valve you do not need to worry about the pin. Also if you have a remote setup for the paintball tank the adapter can thread into the regulator no pin depressor needed. Getting the left handed stem out of the regulator can be tough and might damage it.

My only concern would be the grade of the plastic hose on those remote tank relocators with a valve. Most of that is by no means "food grade" and you still have to worry about chemicals leaching via the co2 gas inflow. Then again I get upset when I have to use any material other than stainless steel.

AGAIN, if you use the one that More Beer has it works for both paintball tanks and std. Co2 tanks. If you are an adept DIY person you will have no problem switching the stem. If you are not a DIY guy, just be gentle and you wont have a problem..

but im guessing if you are a brewer then you are a diy guy..

The remotes use a stainless steel braided line so it's all good. I built a draft box that uses 2 16oz paintball tanks built into the bottom. The tanks have on/off valves and anti-siphon tubes so they can lay on their sides. It will pump 4-5 kegs with both tanks on. It makes life easy for parties and BBQs since there is no large tank to lug around. I have 20ln co2 tanks with siphon tubes in them so I can refill the paintball tanks myself at a cost of about $1 each.
