    Hello, just received my new Concoa 2121331 regulator, I would like to build my first dual stage CO2 requlator to replace old JBJ. Have few questions, first I will need to replace adapter to CGA320. This partical unit has output gauge ranging fro 0-30 psi, I would like to run a bit more than 30 psi for inline gla diffuser, do you think this unit will be able to handle hiegher output pressure if I replace gauge with 0-60, 0-100 psi. And last question, this unit has relief valve, should i leave it alone or replace it with plug.
    All answers will be greatly appreciated. Can someone pointme to right place to by correct CGA320 adapter and what size should I get, opening on regulator where the CGA580 is looks like 1/2" but everywhere i see 1/4" NPT, as I said, I never done anything like this before. Thank you in advance.

    Your CGA port on the concoa 212 is 1/4" npt for sure. You can replace that pressure relief valve with a plug. Not sure about the high pressure low-pressure gauge. I know that if you were to reduce a 0-200 psi gauge to a 0-60, you are fine. Not sure about the opposite direction.
    COngrats oon the purchase! Feel free to PM me.

    Matt,

    Why do we want to replace the relief valve with a plug? Isn't the valve there for a reason???

    tridentair,

    Congrats on the purchase. A very nice regulator...Best of luch with it...

    On some models it's okay to take the relief valve off. It's an option on some regulators (not required).

    Hi, agree with Matt F.

    tridentair, NPT sizes are nominal.
    The actual diameters differ.
    1/4" NPT is actually 35/64" or 0.540".
    So it looks like 1/2". :)

    Thank you guys for your replies, this unit is amazing and solid, I was looking forward to build this regulator, but have to sell it now. The idea was to use it with inline diffuser but it requires at least 30 psi to work properly. This unit can handle only up to 15 psi outlet pressure. I will be putting it up for sale or trade, and will look for the one that can go from 0-40 psi.
