This borosilicate glass bubbler replaces the standard glass mouthpiece on the Wolkenkraft FX Mini Ultra and runs the vapour through a small amount of water before it reaches you. It slides into the same socket as the glass mouthpiece, so no tools or adapters are needed.

The FX Mini Ultra has a short air path and no cooling unit, which means vapour arrives warm at higher settings. Water filtration takes that edge off, so sessions at 200°C and above stay comfortable and the flavour stays clean.

Fill the bubbler before you fit it, never while it is seated, and keep the water just below the small holes at the bottom. Only a little water is needed. The silicone top ring lifts off, which makes rinsing the inside straightforward. The glass is noticeably thick for a bubbler of this size.

Intended for use with: Wolkenkraft FX Mini Ultra.
