NPT is National Pipe Thread. It is a standard of sizing of pipe threads
used in the USA.

I use the Clippard MNV-4k2 - it has a hose barb on one end and a threaded
end on the other. You can either connect it directly to the regulator (like
I did) or make it go inline. To use it inline, you just need the adapter to
adapt the threaded end to a hose barb. To use it inline, you need to remove
whatever "large needle" and if like mine a shutoff valve from the output end
of the regulator. You then need the proper adapters to connect the Clippard
valve to the regulator.

Take a look at this document on my web site for more info and specific
parts. If you are considering connecting it to your regulator, I STRONGLY
recommend you take in your regulator with you so you can be sure to get the
right parts.

For more information on high pressure co2 (I know you have read a lot
already) I have assembled what I think are the best articles on the web on
co2 for planted aquaria.

Hello...
I'm going to the "Fluid Control Products" store tomarrow. It turns out
that
it's a ~half mile from my house...
Anyways, they carry clippard needle valves.Nice.
Can some1 here give me a recommended part number?
Does clippard carry in line needle valves, or do they screw on to the
regulator
itself?
Am I going to need some sort of reducer barb? Are these reducer barbs
common
to
non fishkeepers?

Your advice or input will be appreciated.
Hey, it's only been 6 years of DIY

O.k. after reading Co2 articles for the last 5 hrs and masny beeeers
layter..
I found the actual part number for the clippard needle valve, it's MNV-4K.
I read that I also need "An adapter that connects valve to 1/8" NPT female
fitting" and a 1/8" hose barb.

What is NPT?
Also, what material is CO2 proof tubing?
