The Glass mouthpiece replaces the original bubbler that comes with the Utillian 8 in case yours is worn out. This mouthpiece attaches to the top of the U8 and is lit up by the LEDs found right under where the glass piece is placed. Pay attention when positioning the bubbler so it fits perfectly onto the base of the device. The hole in the mouthpiece must be aligned correctly towards the small slot on the inside wall of the base. When aligned, fill the mouthpiece with water past the two air holes to get the most out of each vaporizing session.
