Are you serious..........do you really think for one minute, that a client would be upset by the appearance of this wand...........it's shiny and clean and clients are very unlikely to even see the jets, or notice the connectors and even if they did...............are they going to stop you in your tracks and refuse to let you in their home, because they don't like the look of " that little brass bit" .........
If it's working..............leave it alone, other than to reverse the male / female connectors, as Mike says.
