GRAV Medium Gravitron Glass Gravity Bong – 14 mm

Feel the rush as thick, milky smoke fills the chamber and drops into your lungs in one smooth, dense hit.

What It Is

The GRAV Medium Gravitron Glass Gravity Bong is a bona‑fide grav that blends classic design with modern durability. Standing at a comfortable height, it features a 14 mm joint and is forged from heat‑resistant borosilicate glass, so you get a sturdy piece that won’t crack under regular use. Water displacement creates that signature milky cloud, while the glass‑on‑glass seal keeps every pull tight and leak‑free. If you’re hunting for authentic glass bongs and water pipes, this model sits at the sweet spot between boutique flair and everyday reliability.

Why You’ll Love It

• Denser clouds: water filtration and diffusion cool each hit, delivering a thick, flavorful plume.
• Rock‑solid build: borosilicate glass resists thermal shock and stands up to daily sessions.
• Easy cleaning: a quick rinse with isopropyl and coarse salt restores clarity in minutes.
• Simple operation: gravity‑based pulls require no batteries or electronics – just load, fill, and inhale.
• Versatile fit: the 14 mm joint matches most bowls and accessories, so you can swap pieces without hassle.

How To Use It

Fill the base until the percolator slits are just covered, grind medium and loosely pack the bowl, then draw slow and steady to pull the smoke into the chamber. When the glass is full, release the chamber to inhale the dense hit. Change the water daily and give the piece a weekly deep‑clean with 91%+ isopropyl and coarse salt to keep flavor fresh.
