That's what I originally thought but I bought a 5/8" dryer line and it was too big for the flare fitting so that's why I am leaning toward 1/2". Unless I am missing something in that a 5/8" OD line fits differently. I am so dam confused at this point I can't keep it all straight. I am basically at the point where I am ripping it all out and bringing it to a plumbing supply and letting them tell me what the hec it is.
So the fitting that you bought 5/8"OD is for 1/2" ID copper whish is 5/8 out side dia and fit's 1/2" inside dia of copper. Hope this help's out
Helps out immensely that is what I was beginning to learn and find out after numerous trips to HD and reading a bit online but you just confirmed it so thank you very much .
I had a 5/8"OD line and was too big, I just bought a 1/2"OD and we'll see if that fits. If not I throw up my hands and everything comes off and goes to a local plumbing supply. Should have prob done in the first place but thought I could figure it out.
