CO2 Regulator barb fitting help please

[sleepy_brewer]

Hi everyone,
Can anyone let me know (by a link if possible) what type of screw on barb I would need for this? My gas tubing is 5/16" and some is 3/8". If I can get the same size barb for both size of tubing I have that would be great. I just want to make sure I order the correct pieces.

It appears that the thread for the CO2 lines 1/2" wide. Any help is much appreciated. View attachment ImageUploadedByHome Brew1444501450.361060.jpgView attachment ImageUploadedByHome Brew1444501464.697768.jpg

I don't know if I am following your question. But, the barb should be 1/16 bigger than the I.d. of the tubing. 3/8 (6/16) barb and 5/16 I.d. tubing. Soak end of tubing in hot water to connect.

I need to find the correct size of fitting that will screw onto the thread pictured. Sorry if I am not using the correct terminology....so the barb I am not as concerned about as much as the female end of the fitting

I went to Lowes and this thread worked so I guess I need 1/4" to whatever size barb I need.

Hmmm....so does anyone have a link to one that would work? I am looking on sites but not sure what measurements are for which. The threaded end I need fit 1/4" female thread and the barn end needs to fit 3/8" or 5/16" tube. Thanks.

I think this is the correct size thread: http://www.kegoutlet.com/swivel-nuts-treaded-to-barbed-for-beer-and-gas-line.html

Hopefully someone can chime in. The swivel nuts on my gas disconnect is a different size than will fit on the CO2 regulator....threaded side.

Swivel barbs are typically for flare thread. You are looking for 1/4 fpt to barb. I only have them in 1/4" tube size.

Thanks Bobby. I found a 1/4" npt to 3/8" barb so hopefully that will work out.
