Here's a video of me tapping the end of the Loc-Line nozzle.  I originally used pliers to hold the other end of the nozzle while I tapped it, but I realized that the pliers were biting into the plastic too much and messing up the socket joint on the nozzle.  So I switched to using tape to keep the nozzle from rotating. (Still have two messed up nozzles that dont stay on as well as they should though. =/ )
