hello. there seems to be a lip at the lower part of the circular opening to which I connect my regulator. While replacing the O-ring in here, I noticed that the circular opening is not perfectly circular. I have circled the flattish lip in green in the photo attached
Would you happen to know what that is? I don't see such a lip and my other cylinders. This is supposed to be in aluminum 80 ft.³ cylinder.
Thank you for your time.
