Actually, after I finished, I realized probably the easiest and best
solution for the male threads would be some fine emory cloth. Since
the male hose ends are formed, not cut anyway, they don't have sharp
bottoms and it's more than likely just some rough edges on the end and
the outer diameter from dragging exposed ends over concrete sidewalks,
etc., that is the culprit. (Of course, that brings up the "don't do
that!" mantra... )
