These 18mm Water Pipe Attachments (WPA's) are compatible with the Mighty, Crafty, Mighty Plus and Crafty Plus. They allow you to pass the vapour produced from your vaporizer through your bong or water pipe which cools the vapour down.
Simply use the WPA to replace the cooling unit, then attach your dry herb vaporizer to your bong or water pipe to cool the vapour produced from your vaporizer.
These will work with any bong or water pipe with a 18mm female connector point.
