12 Port Manifold (for co2)

[jmhart]

To do this you need:

Manifold
1 needle valve per tank(4 tanks means 4 needle valves)
4 bubble counter's

That manifold is a 1/4" NPT so either your needle valves need to be male NPT so they can screw directly into the manifold, OR you can use inline needle valves, with barb fittings attached to the manifold.

You don't need 7 needle valves, as your above post suggested.

I think the manifold is actually 1/8" from what the site said.

12 port manifold $11

Using hose barbs and in-line needle valves you can run a full 12 tanks from this manifold. Input port is 1/8” NPT. Outlet ports are 10-32.

Plugs are $0.30 each. Hose barbs are $0.50 each. In-line adds $2.

So If I want to use inline needle valves, I need the barbs, too? So in order to use inline, the barb needs to attach a hole first, then second, attach the inline valve onto the barb, then the needle valve attached to inline valve?

yes.

if you are going to use inline needle valves, you need a hose barb for each of the needle valves to connect to the manifold. then you hve to plug the remaining holes in the manifold...

have you considered this?

thats a good idea zig lol might hvae to pick one up my self.

 

[The Zigman]

its only $60. I dont think you could build it for $60...

 

[jmhart]

Zig, I've seen those manifolds before, except made for/by JBJ/Milwaukee regs. The needle valve is the same that comes with the Milwaukee reg, which leaves a little to be desired.

Plus, I think it's be cheaper to do it the Rex Grigg/ DIY route.

Oh, the one's I've seen are like $100...$60 isn't bad. There's still the needle valve issue, but if you already use/are ok with that needle valve, then $60 is awesome.

Ebay is full of needle valves. I was thinking of building a manifold for my 4 tanks too...
but most all of my plans are on hold for a while...

 

[jmhart]

I built my 3 port manifold out of swagelok parts...but they were scraps from work.

Wow what is this, zigman? It looks like it has all the needle valves...eh? Tell me all you can about this hardware and what it does
