Grav Labs Bates-Worm Diffusion Pump 12 Inch Dab Rig
The Grav Labs Bates & Worm Outside Diffusion Pump Bubbler is an incredible design collaboration between Grav Labs, Steve Bates & Worm Glass. Water is pulled through the diffusion pump on the outside of the pipe and the glass bead separates your hit into thousands of individual bubbles.
This piece takes dabs to the next level, as it showcases a diffusion pump design and features a separation tube that connects the joint to an outer chamber. After you fill this bubbler up with water and begin to take a hit, the water and smoke begin to flow into the chamber until they meet inside the outer pump. It is then that you truly experience the genius of this piece as the outer pump and marble separate the hit into tons of individual bubbles. The borosilicate glass marble ball also helps to restrict back-flow of smoke / water.
The outer pump tube also doubles as a handle to help grip your piece a little better and prevent accidents! Functions best with approx. 2 inches of water.
