co2 needle valve

[Maximus1]

Hi all,
I'm looking for a good needle valve to control my co2 output. I have a cheap one and do not like it. A few years ago, Petswarehouse carried a real nice, heavy duty one. I can't seem to find it anymore. If you have any suggestions, I would appreciate it. Thanks!

I got mine from MarineDepot for 3 of my reactors, and they are good enough for me, FWIW.

I have the same needle valve but have a different regulator. The valve does not fit on the regulator. I tried using it without attaching it to the regulator but it will not accept the tubing.

If I remember correctly, the needle valve about has an adoptor/bushing that enable it to attach to 1/4 inch MPT. So what is the thread for the regulator? What kind of regulator do you have? I used 3 different regulator, and I have no problem with the 1/4 MPT...

I have an aqualine bushke regulator. I just tried to put it on but the threads do not match. Not sure why. I may look into a flow meter. Thanks for all your help.

Most flow meter does not work well due to the small flow rate. ...
