I did not have to cut down the cartridge housing at all. I did screw the street elbow onto the pipe first then used a wrench on that to screw the pipe into the tap.

I'll take some pics of the finished product.

i'm not sure that i clearly see what we are doing here. the air chuck hack is simply so you can charge the keg with CO2 without having to use the 16g cylinders?

can i just buy one of these and fill it with homebrew and charge it a 16g cylinders and have a "mini-keg" for my beer?

Yes, lots aof videos on youtube that show you how. I think the hack here is just to bypass the 16gram cartridges. They can add up in $ and can be hard to find for some. I have also seen videos of someone who cut the 16 gram cart. to be a sleeve for an 8 gram cart. So the 8 gram cart. can fit. They are cheeper and easier to find for some.

Thanks for that clarity. I guess it could be an easy way to begin a keg operation. So you've definitely got my attention. Thanks for sharing the knowledge!

Here is a picture of my solution.

Using the original part of this thread with the 1/8" MIP x 1 1/2" pipe and the 1/8" MIP street elbow is the key for me. From there my CO2 charger connects right up.

Nice and easy.

Thanks for the pics. I know exactly what I did wrong and will correct it.

So are you able to force carbonate with this method?

Looks pretty good. Not to hijack but this seems like an easy way to rig them up also.

I believe I could force carbonate if I wanted. In my case I fill from my keg and go from there.

I couldn't help myself and I threw together two video's on youtube for those whom may not be mechanically inclined on how to tear down and rebuild the Coors/Miller home brew system. It was a first go at it and after drilling - i found a small plastic plunger that likely is a check valve to limit potential liquid leaching to the air cylinders. That said, there was no leaking when removed... Also, just want to point out that the Watts copper/brass connectors have lead (Pb) at 0.25% or greater... it's an assumption that simple air flow through the pipes will not transfer Pd (likely a decent assumption), however if they get any back-wash particularly if your brew is acidic - won't kill you but over long term contact... not good for ya!

Part 1 shows how to break down the device, the parts needed, and how to remove the side cap and drill it out.


Part 2 is the step by step rebuild to link to a quick valve... let's not forget to purge any O2 which is also discussed.

I hope they are helpful to anyone looking to do a tear-down more than just the CO2 cartridge replacement... (oh - saw some chatter regarding non-food grade vs. food grade... they usually put a silicon oil in the airsoft/paintball systems - you'll probably get a foul taste and an oil slick - which will kill head retention.)

Great vid!

I have a couple of these that I was planning on hooking up to co2 by modding a spent cart, but after just 3 carts in one the seal was already starting to fail, so I think this method is going to be a lot more reliable.

That regulator you got there is one of a few that I can get locally. What size fitting does that screw on to? It doesn't look like it'd fit on my 2.5lb co2 tank without some sort of conversion.
