These 14mm Male WPA (Water Pipe Attachments) are made to be compatible with the filling chamber on your Volcano Classic. One end of the WPA is tapered to fit any 14mm Female water bubbler. The end that inserts into the filling chamber of your volcano has a silicone sleeve wrapped around it, which forms an airtight seal when inserted into the top of the chamber.
The WPA will fit into any 14mm Female connection point, and most glass bubblers will have either a 14mm or 18mm connection point.
This WPA is priced individually.
Please note, the ERUPTOR bubbler, easy valve filling chamber, and balloon in these pictures is not included in this price, but all are however available for purchase under 'ACCESSORIES - GLASS BUBBLERS and VAPORIZER PARTS - STORZ AND BICKEL
