The VOLCANO glass bubbler has been carefully created to fit perfectly with your Volcano Hybrid or Volcano Classic/Digit.

Fitting: Remove the blue O-ring on the filling chamber of your Volcano, replace with a black O-ring (2 x supplied) simply attach the bubbler to the Heating Chamber, and then insert your balloon adapter onto the other end.

As the vapor passes through the water in the bubbler, it is instantly cooled, and then forced into the balloon, allowing the user to fill balloons on the hottest temperature settings, without irritating the throat!
