These 18mm Water Pipe Attachments (WPA's) are compatible with the Arizer Solo2. They allow you to pass the vapour produced from your vaporizer through your bong or water pipe which cools the vapour down to a temp that gives maximum flavour with no irritation on the throat, which ultimately allows the user to take bigger rips.
Simply use the WPA to replace the glass aroma stem, 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.
