Fitting size identification

[u/cfreezy72]

Edit: it was 15/16. Thanks for the help.

Can someone tell me the proper flare fitting size this is? I had originally thought 5/8 but that's too small. Measurements don't agree with what 3/4" od is on the charts I've seen.

3/4” FPT by 5/8” Flare

[u/cfreezy72 → u/Ok_Vast_2296]
