GRAV Gravitron 2.0 Gravity Bong - 4 Sizes
⭐ Expert Product Summary
The GRAV Gravitron 2.0 Gravity Bong System is an all-glass pressurized smoking system re-engineered with a 5x increase in glass thickness, upgraded platinum-cured silicone grommets, and precision ground glass joints for maximum vacuum efficiency. Operating entirely on hydrostatic displacement and gravity, this system pulls zero-waste, milky clouds into an internal glass bottle before forcing dense, pressurized smoke directly into the lungs upon descent. Available in the compact Medium 9" (14mm joint), the flagship party-sized Large 11" (19mm joint), and the vintage-inspired Monarch 12" (14mm joint) with scalloped artisan fluting, every Gravitron 2.0 model includes an ergonomic neck-lifting flange and a matching glass funnel bowl slide.

Hydrostatic Vacuum Displacement & 5X Glass Thickness: GRAV Gravitron 2.0 Features
Harness pure physics and zero-loss combustion with the completely redesigned GRAV Gravitron 2.0 Gravity Bong System. As the world's first commercial all-glass gravity smoking pipe, the original Gravitron revolutionized session efficiency; now, version 2.0 elevates the experience with a massive fivefold increase in borosilicate glass thickness, eliminating the fragility of legacy designs. Built from heavy-duty, thermal-resistant borosilicate glass, the Gravitron 2.0 delivers commercial-grade impact resistance, thermal tolerance, and a 100% chemically inert airpath that preserves the purest terpene profiles without plastic degradation or metallic aftertaste.
Operating the Gravitron 2.0 is effortless and visually hypnotic: fill the heavy outer base halfway with water, pack the included ground glass funnel bowl, spark the herb, and slowly lift the inner glass bottle. The upward hydrostatic vacuum pulls every micro-particle of dense, unadulterated smoke into the chamber with zero smoke loss to the surrounding room. To clear, remove the bowl, place your mouth over the mouthpiece, and push the bottle back down into the water. The displaced water acts as a pneumatic piston, pressurizing and driving dense, cooled clouds directly into your lungs with effortless force. Upgraded with an ergonomic molded lifting flange at the neck and a food-grade platinum-cured silicone grommet that creates an airtight seal, the Gravitron 2.0 is the undisputed pinnacle of gravity bongs for solo micro-dosing or legendary group sessions.

GRAV Gravitron 2.0 FAQs
How do I operate the GRAV Gravitron 2.0 for maximum efficiency?
Fill the outer glass base roughly halfway with room-temperature or cold water. Insert the inner bottle until it rests near the base, then pack ground flower into the included funnel bowl slide and place it into the neck joint. Apply a flame to the bowl while slowly lifting the inner bottle upward by its ergonomic neck flange. The vacuum created by the falling water level inside the bottle will pull dense smoke into the chamber. Once filled, remove the bowl, seal your lips over the mouthpiece, and inhale while gently pressing the bottle back down; the water level will rise, forcing the pressurized smoke into your lungs.
What is the difference between the Medium, Large, and Monarch models?
The Medium Gravitron 2.0 is 9" tall with a universal 14mm joint, ideal for personal daily sessions and smaller lung capacities. The Large Gravitron 2.0 is 11" tall and utilizes an extra-wide 19mm joint for high-volume smoke extraction and large party groups. The Monarch Gravitron is 12" tall and features vintage scalloped fluted glass architecture, a 14mm joint, and an elevated collector aesthetic while matching the high-potency performance of the classic lineup.
What improvements were made in the Gravitron Version 2.0?
The Gravitron 2.0 redesign includes a fivefold increase in glass wall thickness, standard female ground joints (14mm or 19mm) that fit any aftermarket bowl slide, a molded glass lifting flange at the top of the neck for easier handling with wet hands, and a heat-resistant platinum-cured silicone grommet that ensures a leak-free, airtight seal at the base.
What is the best way to clean the all-glass Gravitron?
Separate the inner bottle from the outer base and remove the silicone grommet and glass bowl slide. Pour 91%+ Isopropyl Alcohol and coarse sea salt into both the base and bottle, scrubbing with a soft bottle brush or swirling the mixture to strip away interior resin. Rinse all glass components thoroughly with warm tap water. Wash the silicone grommet separately with warm water and mild dish soap before reassembling.
