A Water Pipe Adapter is often considered to be the best accessory for your device. These Universal WPAs in particular allow you to use your device with almost any bong with a 10mm, 14mm or 18mm joint-type, which is all of the standard bong/water pipe joints. Made out of borosilicate glass to be far more heat resistant than is necessary. This is great as water-cooling is the undisputed best form of cooling for any dry herb device. It is more effective than any glass beads or even cubic zirconia. Not only does it give the most cooling- but it also rehydrates the vapour. This makes your hits so much smoother as its the dryness and the heat of the vapour that can irritate your lungs and cause coughing- which is overall better for your health. Additionally it is much easier to clean this WPA and your bong/water pipe than cleaning a stem with glass beads or cubic zirconia, you can also clean this glass with alcohol without causing discoloration unlike the black plastic of the original cooling unit.
