The Mighty/Crafty Water Pipe Adapter is intended for use with the Mighty or Crafty Vaporizer in place of the cooling unit. This adapter works with both 14 mm and 18 mm female bubblers/water pipes. The Mighty/Crafty Water Pipe Adapter is easy to use. You just have to remove the cooling unit from your device and attach the adapter. Twist it to lock it into place. Please note: the locking threads are made with flexible rubber to ensure vaporizer’s plastic body will not be damaged while vaping. This means that instead of stressing the plastic, the adapter will disengage from it. To ensure nothing spills in the event the adapter disengages, it is advised that you use dosing capsules.
