These 18mm Water Pipe Attachments (WPA's) have the larger medication chamber and are compatible with the Arizer Solo 3 only. They allow you to pass the vapour produced from your vaporizer through your water filtration device which cools the vapour down to a temperature that gives maximum flavour with no irritation on the throat, facilitating easier use of your medication.

Simply use the WPA to replace the glass aroma stem, then attach your dry herb vaporizer to your water filtration device to cool the vapour produced from your vaporizer.

These will work with any water pipe with a 18mm female connector point.
