help the physical act of playing slurs, or the response of the notes, but it can help reduce a slight popping noise (sort of like when a person smacks their lips slightly when speaking into a microphone) that happens when the air pressure of a valve's tubing is different than that of the open horn. In other words, it won't make your non-perfectly-executed slurs sound better, but it will help a well done slur sound more pure.
