Hi Peter
May I ask if that is a new flexi pipe & do you have a better picture ?
Your image is quite difficult to view in any great detail.
Here's a typical female pipe flare
I find it best to avoid over cooking the forming of the female flare, tends to make them a little weak & troublesome to seal.
I know these are not flexi pipe ends but they do represent the kind of ends usualy found on flexi pipes
Female left & male right
It has been my personal experience that the male end is by far the most common end to find at the rigid pipe end.
