18mm - 18mm Female to male adapter. Perfect for Freeze Pipe Bubbler customers interested in using our E-Nail or Ash Catcher on their Bubbler. 

Given the wild popularity of our Bubbler creating this adapter became a popular request. When either attachment is placed on the Bubbler we do NOT recommend setting the Bubbler down. And if you do, please be careful. 

With that said, it works well and adding either attachment to your Bubbler is a real fun time.  

Use the drop-down menu to select just the adapter or adapter +  combos. Note that any Bubbler combo listed here INCLUDES the adapter
