GRAV® Medium Upright Bubbler (7" Heavy-Duty 44mm Borosilicate Glass Water Pipe w/ Fission Downstem)

The GRAV® Medium Upright Bubbler stands tall at 7 inches, offering a sophisticated blend of scientific function and minimalist style. Crafted on heavy-duty 44mm tubing, this piece is built for both durability and a premium feel. It features a specialized fission downstem that expertly diffuses smoke through water, cooling your hits for a smooth, flavor-forward experience.

Designed with the user in mind, the fission downstem is securely fixed inside the chamber to prevent breakage and ensure long-term reliability. The angled mouthpiece serves a dual purpose: it provides an ergonomic draw position and acts as a built-in splashguard to keep water from reaching your lips. Ready to use immediately, this bubbler comes with a 14mm cup bowl and is easily convertible for concentrate use.

This 7-inch scientific glass hydro-vessel serves as an essential, high-utility expansion for your active glassware catalog. Designed with heavy-wall 44mm tubing, a 90° joint architecture, a fixed fission percolator engine, and a high-stability flat base, it delivers immediate tabletop balance and splash-free draw performance. Incorporating this GRAV® Labs creation into your daily routine introduces a precision water circuit that pairs clean American-engineered design with smooth, moisture-conditioned draws.
