Grav Labs Gravitron Gravity Pipe

🌪️ The Gravitron® – The Original Glass Gravity Bong, Reinvented

Available in Medium (9") and Large (11")

First released in 2004 and perfected over the years, the Gravitron® by GRAV is the world’s first and finest all-glass gravity bong. Available in two sizes—Medium (9") for personal sessions and Large (11") for party-ready rips—this sleek, high-performance piece uses gravity and pressure to deliver thick, potent hits with zero waste.

Unlike makeshift gravity bongs made from bottles and buckets, the Gravitron is all class. No plastic. No mess. Just scientifically engineered glass, airtight design, and powerful, efficient performance.

🔍 Features & Benefits

• All-Glass Build: Both sizes are crafted from 5mm thick borosilicate glass—extra-durable and heat resistant.

• Closed System Design: Smoke stays fully contained in the chamber, ensuring maximum efficiency and zero loss.

• Platinum-Cured Silicone Grommet: Protects glass-on-glass contact at the base and ensures a secure, airtight seal.

• Flange Grip: The top of the inner bottle features a thick glass flange, making it easy to lift and control.

• Includes Funnel Bowl:

  • Medium: 14mm bowl

  • Large: 19mm bowl
    Both use standard male joints, so you can customize with your favorite pieces.

• Easy to Clean: Straight sides and a minimalist design make cleaning quick and painless.

🚀 The Gravitron Experience

Both versions use the same simple but powerful process:

1. Fill the base halfway with water.

2. Pack the bowl and insert it into the bottle neck.

3. Light while lifting the bottle, filling it with dense, milky smoke.

4. Remove the bowl, place your mouth on the mouthpiece, and lower the bottle to enjoy a smooth, pressurized hit.
