Send 2 photos of the male coupler end: 1) a side view, and 2) a measurement across the male end diameter — calipers are best, a tape measure works too. We’ll reply with your size.

Hold the tape flat and straight across the end of the male coupler, with the hook lined up on one edge, so we can read the marks.
