Large Gravitron®

The GRAV Large Gravitron uses gravity and water displacement to create thick, milky smoke through its upgraded borosilicate glass construction, which is five times thicker than previous versions. This closed-system design features a platinum-cured silicone grommet at the base contact point, a GRAV 19mm Funnel Bowl that accepts standard male fittings, and a neck flange for easy handling during operation. The straight-sided chamber design allows for efficient cleaning, while the gravity mechanism eliminates the need for manual draw effort.

This closed-system design keeps all your smoke contained until you're ready to blast off, making it an epic bud-saver. Hits are thick and milky with no effort to draw—gravity does all the work.

And when you're done, the simple design and straight sides make it a breeze to clean.
