GRAV Gravitron
GRAV
The GRAV Gravitron is an all-glass gravity water pipe engineered for dry botanical materials. Utilizing fluid dynamics, this two-piece system uses water pressure and gravity to draw and compress vapor into a closed-system chamber. Constructed from thick 5mm borosilicate glass, it features a platinum-cured silicone grommet to prevent friction and ensure a tight seal. Available in both Medium and Large sizes, this device offers a reliable, electronics-free extraction experience for users seeking consistent, high-volume tabletop operation.

The GRAV Gravitron is an all-glass gravity water pipe designed for the consumption of dry botanical materials. Utilizing principles of fluid dynamics, this two-piece system relies on gravity and water pressure to draw in and compress vapor before inhalation. Manufactured from clear, 5mm thick borosilicate glass, the current 2.0 version features structural enhancements to improve durability during operation. By submersing an inner glass bottle into a cylindrical water-filled base, users can generate a vacuum that ensures an efficient, closed-system draw. The unit is available in multiple sizes to accommodate different volume preferences for tabletop use.
Fluid Dynamics Operation
Operating this device utilizes a purely physical mechanism rather than electronic heating elements. By pulling the inner bottle straight upward out of the water-filled base, a vacuum is created that pulls vapor downward. Pushing the bottle back down forces the pressurized vapor upward for inhalation without loss of volume. This relies strictly on gravity and water pressure to effectively process your dry botanical materials.
Protective Silicone Grommet
To improve structural integrity and protect the glass components during use, the bottom rim of the internal bottle features a platinum-cured silicone grommet. This specialized silicone gasket acts as a reliable buffer that prevents direct glass-on-glass friction between the inner bottle and the outer base. Additionally, this gasket helps maintain a tight internal seal to ensure consistent pressure and a steady draw during the extraction process.
Borosilicate Glass Construction
Both the outer base and the inner chamber of the device are manufactured from 5mm thick borosilicate glass. This clear, heavy-duty material offers high resistance to thermal stress and mechanical impact compared to standard glass. The upper neck of the inner bottle includes a flanged rim, providing a designated, secure grip area for the user to safely lift and maneuver the glass internal chamber during operation.
Size and Volume Variations
The device is produced in two distinct configurations to accommodate different capacity requirements. The Medium version stands 9 inches tall with a 3.25-inch width and utilizes a 14mm female joint. The Large version measures 11 inches in height with a 4-inch width, featuring a larger 19mm female joint. Both variants operate the exact same way and include a compatible male funnel bowl for your material.
