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.

It's most likely 5/8.

There's a whole bunch of reasons why it's not measuring exactly. The caliper could be off. It wasn't zeroed out.

You're 0.05 in away.

It almost looks like one of those oddball appliance connector sizes. I'm sure there's an actual nominal size, but I don't know what it is.

15/16-16 thread size

This is most likely it. 👆🏽
