  • V2 thick glass construction: 5x more glass thickness than the original Gravitron for improved durability and longevity.
  • Platinum-cured silicone grommet: Creates an airtight seal between bottle and base, maximizing efficiency every hit.
  • Standard ground joint: 14mm (Medium, Monarch) or 19mm (Large, Breathe Again) accepts any compatible male funnel bowl.
  • Flange neck design: Flared rim at the top of the bottle makes lifting and lowering the chamber easy and controlled.

Description

The GRAV Gravitron is the world's first all-glass gravity smoking system, built from borosilicate glass with an upgraded V2 design featuring 5x more glass thickness and a platinum-cured silicone grommet for a tighter seal. Available in four sizes — Medium, Large, Monarch, and the limited-edition Breathe Again collaboration — it's one of the most efficient pipes on the market with virtually no smoke lost in the process.

Operation is straightforward: fill the base halfway with water, pack the bowl with dry herb, light it while lifting the bottle, then remove the bowl and inhale as you slowly lower it back. The gravity and water pressure do the work, delivering a dense, pressurized hit that would take significantly more material to achieve through conventional smoking.

FAQs

  • How does the Gravitron work? Fill the base with water, pack the bowl, light it while lifting the bottle slowly, then remove the bowl and inhale as you lower the bottle back into the water. Gravity and pressure fill the chamber for you.
  • What size bowl does the Gravitron use? The Medium uses a 14mm funnel bowl; the Large and Breathe Again use 19mm; the Monarch uses 14mm. Each unit includes the matching bowl.
  • Can I use any bowl with it? Yes — the ground joint accepts any standard male funnel bowl in the matching size (14mm or 19mm).
  • How do I clean it? Disassemble the bottle from the base. Rinse both pieces with isopropyl alcohol or soak for stubborn residue. The silicone grommet can be removed separately for cleaning.
  • What's different about the Monarch? The Monarch is 12" tall with a scalloped glass bottle design, giving it a larger chamber and a more distinctive look compared to the standard models.
  • What's the Breathe Again edition? A limited collaboration with the Pleasures streetwear brand — same function as the Large Gravitron with co-branded art on the glass.
  • Are replacement parts available? Yes. GRAV sells replacement bottles and bases separately for the Medium, Large, and Monarch models.

  • What is a gravity bong? A gravity bong uses the downward pull of water to pull smoke into a chamber — rather than relying on your lungs to draw air through. The result is a dense, concentrated hit with very little material needed.
  • Borosilicate glass: The same glass used in laboratory equipment. It handles heat better than standard glass and is far less likely to crack from thermal shock during use or cleaning.
  • Ground joints: The bowl connects to the Gravitron via a standard-size ground joint — a precise glass-to-glass fit. Any compatible male bowl in the matching size (14mm or 19mm) will work.
  • Efficiency and dose: The Gravitron is considered one of the most efficient smoking devices because the pressurized delivery captures nearly all smoke in the chamber before inhalation. Less material goes further.
  • Choosing a size: The Medium (9") is portable and solo-friendly. The Large (11") produces bigger hits and is better for groups. The Monarch (12") maximizes chamber volume for the largest sessions.
