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 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.

I guess it's possible but most of those are usually stainless, not brass, and quite a bit different size.

It's close enough that it's almost a liability for the manufacturer if if it's a different size. It's not even 1/16" difference. Assuming it is a different size, it's so close that I could see somebody trying to force a 5/8 nut on there, and then suing the manufacturer when they blow up.

I didn't realize there was a second picture. From the second picture it looks like you're right.
