Manifolds allow you to have one CO2 tank with multiple lines. Each line can be turned off individually without affecting flow to other kegs. Each ball valve contains a check valve that ensures no beer or gas can flow between the two kegs. The barbs are all 5/16", standard for gas line in the beer industry.
I first bought the 2-way manifold and quickly realized I needed to upgrade to 3 and drilled another hole in my fridge for a third tap. I use this in conjunction with a few sets of: 'Beer & Gas Tubing Quick Disconnect - In-line W/ Shut-off'. It's great, I can swiftly connect and dispense any number of kegs up to three with a single tank as long as they're dispensed with the same pressure, which so far hasn't been an issue.
It's solid & heavy, leak free, compact and does the job.
I don't know how the check valves should function but when I connect a new keg (0 psi), gas and sometimes liquid is sucked up through the other lines that are connected. I now close the other valves when connecting a new keg and this of course solves the problem.
i'm sure there are cheaper options i could jerry rig myself if i wanted to, but i never knew how much i would be switching gas lines to my 3 kegs on and off. this makes it super easy and i'm confident these will always hold a gas-tight seal when off.
Finally, organized gas lines! Decent quality product
I bought this manifold last year. It worked great for a while, but then an internal seal in one of the valves failed, and the valve developed a serious leak. I ended up having to replace that valve. I wish the original valves were of higher quality.
When I hooked this up to my co2 regulator I discovered that one of the T blocks had a crack in it where it had been over tightened.For the price I paid I would think it would have been leak tested before shipping. It is not worth my time to send it back so I guess I will just eat it.
I bought this for my keezer project. I hooked it up to two kegs, a 1/4 and a 1/6. We went through these pretty quick and I connected two more kegs of the same sizes. Within a week of connecting the new kegs, my CO2 tank was empty. I knew I had to have a leak. After refilling my CO2, I started troubleshooting to find the leak. I placed the manifold into a bucket of water and found numerous leaks between the pre-assembled joints. I had to rebuild the whole manifold. I mistakenly tightened a couple of joints too tight and cracked a couple of the brass blocks; which I just ordered. Be careful if you when tightening if you have leaks. I found the leaks by setting my regulator to 20 psi.
I've been using the manifold for a few years now and I'll say it's held up pretty well, especially for the price. I did have one valve stop working though, probably due to user error of some sort.
The piece of pot metal that connects the knob to the ball in the valve and also acts as a stop for the knob broke. This made the knob unable to twist the ball in the valve. I repaired it by adding another in-line ball valve in front of the broken one(cheap repair) so that the check valve was still utilized in the broken valve. Overall, I'm pretty happy despite the minor set back.
Got one of these for my keezer build. Works great! When I realized I could get six kegs in my keezer it was nice that I could just get another and add it on. I've had leaks in my system but never from these.
