Co2 Tubing Question

[noahcw]

Hey Everyone,

I am looking to get standard aquarium co2 tubing to fit on to the output of this regulator, Is there a trick or an adapter I can buy to do so? Or if you have any other advice, please let me know!

You need to replace that whole output piece with a CO2 needle valve.  The needle valve will allow you to fine tune the amount of CO2 going into your tank.

[noahcw]

Like the entire regulator?

[lucius]

No, you just need to replace the circled piece.

Like the entire regulator?

That output valve is a ball valve that cannot handle the fine control requi9 for injecting co2 into aquariums.
You will need to remove it from the regulator output port which is female 1/4 NPT thread.
You will then need a 1/4 NPT to 1/8 NPT reducing bushing which will allow for assembly of a 1/8 NPT   solenoid if you desire one or a 1/8 NPT needle valve .
The1/ 8 NPT parts are much more common for use in our hobby.
The reducing brass bushing  and other brass fittings are easily found at Ottawa Fasteners ( 2 locations in Ottawa)
JL Aquatics have a suitable solenoid and needle valve.
I will try and post some links when have some more time.

You will likely find all those required parts at boone plumbing as well. 4 locations around town. One in Kanata too.

Here are a few links, as mentioned, JL Aquatics has some suitable solenoid and needle valve, i have no personal experiences with the pieces linked.
One thing to note is  needle valves vary in the amount of fine control offered.

The following , i have personal experience with and have found them to be both reliable and adequate

For brass fittings ,l  highly recommend Ottawa Fastener supply for small quantities and diy`ers

As an example here is the reducing bushing required

Here's a good thread from charlie that has some more details and pics on the assembly process.  The difficult part is actually sourcing the parts needed.
