16" Spiral Bong

The first pull from this 16‑inch spiral bong feels like a crisp breeze through polished glass, instantly cooling every hit.

What It Is

The 16" Spiral Bong from the PILOT DIARY collection is an authentic water pipe built from 9 mm thick borosilicate glass. At a solid 16.0 inches tall, its spiral beaker not only looks striking but also houses a standard ground‑glass joint for easy bowl or ash‑catcher swaps.

Designed for reliable performance, the bong’s thick glass resists thermal shock, while the built‑in percolator slits diffuse water for a consistently smooth, cool draw. It’s the kind of piece you’ll reach for whether you’re chilling at home or sharing with friends.

Why You’ll Love It

• Durable construction: 9 mm borosilicate glass stands up to daily use without cracking.
• Cool, clean hits: Water filtration and spiral diffusion chill each inhale, preserving flavor.
• Easy maintenance: Rinse with isopropyl and coarse salt; the simple geometry keeps residue out of hard‑to‑reach spots.
• Versatile compatibility: Standard ground‑glass joint lets you attach bowls, ash catchers, or carb caps from our glass bongs and water pipes lineup.
• Authentic branding: You’re getting the genuine PILOT DIARY design, not a re‑label or knock‑off.

How To Use It

Fill the base with water until the percolator slits are just covered, pack a medium grind loosely into your bowl, and draw slowly for a steady, flavorful stream. Change the water daily and give the piece a weekly deep clean with 91%+ isopropyl and coarse salt to keep the taste factory‑fresh.
