Voopoo Uforce Bubble Glass and Tank Extendor
The extension glasses for the Voopoo UForce tank work a little differently to most. Due to the shape and size of the tank for any of the extension glasses to fit you will also require an extension chimney and for the larger glasses you will require 2.
So for the 5ml extension glass only 1 extension chimeny will be required. As for the 5.5ml and 8ml glasses you will require 2 extension chimneys.
