DIY Inline CO2


Anyone have any DIY inline CO2 projects completed with pictures that they can share? I'm looking for a good way to build my own.
Anything i should look for, or look out for?

Search the DIY Forum and I'm pretty sure you will find something.

Google search gave me better results apparently.
If i am building my own, where is best location to tap the co2 inlet into the cylinder? Middle? bottom? I'm planning to tap a ceramic disk co2 diffuser into a cylinder.

I would think the bottom. This would give the remaining space for the CO2 to dissolve in the cylinder before exiting to the tank.

I agree, but why would they have it like in the picture here:

Now i know that 100% silicone is the one to use as sealant, but is there any brand that is easy to remove, should i need to remove it?
I am thinking i will just go with pvc pipe instead of clear tube and just build a top piece that is screwed down which will be clear from plexi glass.

Also, has anyone experienced with using liquid electrical tape to coat the inner pieces of the fittings with it to minimize the brass oxidation/corrosion?
See below.

and anyone know if the silicone i got will work fish safe as a sealant for the co2 inline cylinder?

i bought a piece of clear PVC piping (about 10 or 12 inches long) a while back for this project, but never followed through. i can sell it to you if you're interested. i also have some random fittings that might help.

I already went through with the setup i got. I'm using 4.5inch pipe. Pretty wide. But thanks for the offer!
