So you’re trying to connect the 1/8”metering valve to the elbow, right? What size is the elbow and are you trying to connect the metering valve to the male or female end of the elbow?

Did your 1/8” metering valve come with the compression nuts for both ends and their and ferrules?

So you’re trying to connect the 1/8”metering valve to the elbow, right?

Yes.

And also add a 1/4" push connect fitting to the outlet of the metering valve.

What size is the elbow and are you trying to connect the metering valve to the male or female end of the elbow?

1/8" elbow - i want to connect to male side of elbow.

Did your 1/8” metering valve come with the compression nuts for both ends and their and ferrules?

Yes but I lost some of the ferrules. Jeez they're tiny.

Thank you for your help.

Yes definitely gets messy quick! Literally thousands of fittings on the Swagelok site, and I don't know my gas fittings terminology....

AFAICT need the tube size..Could be metric.. could be us.
Isn't there a large number engraved on the other side of the metering valve?

 

[oreo54]

you can get male or female ends.. males are easier to find.

I purchased the valve as "1/8 in" (came with compression fittings on the ends. Can we assume this is the "tube size"?

No part #....

These two parts are the same - correct?

 

[oreo54]

No not really .. Need the i.d of the inside of the compression part so that tube end fits correctly.
Weird there are no model numbers on it.

Can't see that working..Your going compression to compression , only bumping tube size from 1/8 to 1/4.
Not compression to 1/8 npt.

 

[Water Dog]

My recommedations are assuming that you have a 1/8” metering valve.

These two parts are the same - correct?

Sorry, second part is supposed to be a port connector. Just edited the post to reflect that

This part is to go from the 1/8” the metering valve to the CO2 tubing.

Thank you! What fitting would I need to do the JG style fitting instead of the 1/4" compression?

....Connecting metering valve output to this....

I dunno. I only use the 1/4” tube compression fittings on all of my builds for the CO2 tubing connection. I keep a bunch of 1/4” ferrules on had should I ever need to change out the tubing.

Not sure if you saw my thread, but I have a walk through of a regulator build here...
