The number one is a needle valve for aquarium, or then sold me like that. And the second is argon valve (i think that this one has a pressure chamber)

Attach the second one to the cylinder and then run some tubing off of it and get yourself a in line needle valve. I don't think you have the right setup there to even use the first one. Inline needle valves are attached by tubing and nothing else. looking at the picture closely you could use the one from the first picture but I think that the one from the second picture would be better with and inline needle valve.

Thanks for the answer. I have a metal piece to adapt the first one directly. It work but i didn't try it. Did you say that connecting both of them in line? first the needle valve in the input of co2 tank, and the other valve in the output?

Thats the best configuration?

thanks

Attach the one in the second picture to the cylinder and then run some tubing off of the tubing port on it and then attach a inline needle valve followed by more tubing that goes to your reactor/diffuser. I think you need to purchase a inline needle valve.

there is a link for a inline needle valve. The inline needle valves are connected using tubing only.
