Inverter Flare or NPT Pigtails?

I am really confused - we have a Cavagna 2 stage auto changeover regulator & I cant figure out which type of pigtails they are?
I have attached a picture - please help.

Thanks,

Glenn

Typically the outlet is 3/8 inch NPT. Check your model number against the manufacturer's specification sheet for confirmation though.

Those are pipe thread pigtails.

Kevin - thanks!!! I have a Type 924 NRV it says Outlet connection is 3/8 NPT.
Is the outlet connection where the pigtails screw into the regulator?

Do the pigtails screw into the inlet or outlet connection?

The pigtails thread into the outlet ports.

Ok - just seems backwards since gas is flowing from a tank into the regulator then out to the AS....

Actually Iím backwards (not the first time either I might add). The outlet is the single. The inlet is the double. Refer to the photo of your regulator in the pdf file.
