GRAV® Smoke Upline Water Pipe

The GRAV® Smoke Upline Water Pipe doesn't filter smoke the way a traditional bong does — it filters it progressively. Instead of a single perc at the bottom and a straight tube above it, the Upline features a ladder-style chamber where smoke and water rise together through multiple stacked bubbler sections, each one cooling and filtering the draw a little more before it reaches the next. By the time vapor arrives at your lips, it's been through a series of small, controlled percolation stages — not just one.

The result is a draw that's smoother, cooler, and more refined than what conventional single-perc or even dual-perc designs can deliver — with noticeably less splash-back thanks to the stepped chamber geometry. Built from smoke-tinted glass that gives the piece a dark, understated aesthetic, and equipped with an integrated downstem that doubles as an ash catcher, the Upline is engineered for focused sessions where vapor quality is the priority. Ships with the iconic GRAV® 14mm Octobowl.

Features

• Ladder Perc Design — Multiple stacked bubbler sections create a progressive percolation path. Smoke and water climb through each stage together, cooling and filtering incrementally for a smoother, more controlled draw than single-chamber designs can achieve.
• Progressive Cooling — Each rung of the ladder adds another layer of water contact and temperature reduction. The further the smoke travels up the chamber, the cooler and smoother it gets — delivering a refined hit by the time it reaches the mouthpiece.
• Minimal Splash-Back — The stepped chamber geometry naturally contains water within each section, preventing it from rising all the way to the mouthpiece even on harder draws. Clean lips, every hit.
• Integrated Ash-Catching Downstem — The built-in downstem doubles as an ash catcher, trapping debris before it enters the water chamber. Keeps your water cleaner for longer and reduces the frequency of deep cleans.
• Smoked Glass Finish — Tinted smoke-colored glass gives the entire piece a dark, sophisticated look that hides water lines and light residue between sessions. Subtle, refined, and unmistakably GRAV®.
• GRAV® 14mm Octobowl Included — Ships with GRAV®'s signature eight-sided flower bowl — ergonomic, easy to grip, and designed for even airflow across the pack.
• 14mm Female Joint — Standard 14mm connection compatible with a wide range of aftermarket bowls, ash catchers, and accessories.

Why Choose the GRAV® Smoke Upline?

Most bongs filter smoke in one shot — a perc at the bottom breaks it into bubbles, the bubbles rise through a single column of water, and that's it. The Upline takes a fundamentally different approach. Its ladder perc forces smoke and water through multiple small chambers in sequence, so instead of one pass through one body of water, you get several shorter passes through several separate pools. Each stage strips a little more heat and a little more harshness. The cumulative effect is a hit that's noticeably smoother and cooler than what even complex multi-perc bongs can deliver — with almost zero splash.

The integrated downstem that doubles as an ash catcher is a detail that shows how much thought went into this design. Instead of adding a separate accessory to keep your water clean, the Upline catches debris before it enters the chamber as part of its built-in architecture. Fewer accessories, fewer failure points, cleaner water.

The smoke-tinted glass isn't just an aesthetic choice — though it does look exceptional. The dark tint naturally masks water lines and light residue between cleanings, keeping the piece looking sharp even during heavy rotation. It's a daily driver that still looks presentable on a shelf without constant maintenance.

Ships with the GRAV® Octobowl — one of the best-designed flower bowls on the market, with eight-sided geometry that's easy to grip and promotes even airflow across the pack. This is a complete, ready-to-smoke setup from one of the most respected names in glass. If you've been smoking on conventional percs and wondering what else is out there, the Upline is the answer.
