Stündenglass Gravity Bong Store

A Stündenglass is a gravity-powered water pipe, which the brand now calls a Gravity Infuser. You load a 14mm bowl or accessory, rotate the unit 360°, and falling water pulls smoke or vapor through water filtration into the top globe. Rotating it again pushes the hit out of the mouthpiece with forced air, so you do not have to pull hard on the draw.

For people who want smooth, water-filtered sessions, a statement piece for the coffee table or a contactless option for groups, many owners feel it is. It costs more than a standard bong, and it needs regular cleaning to keep rotating smoothly. If you want the newest design, choose the V3; if you want the longest listed warranty or a travel case, choose the Classic or Kompact.

Yes, with the right attachment. Every model uses a 14mm connection, so you can add the Stündenglass Modül with its concentrate tank or an e-nail such as the G Pen Hyer. The V3 product page also lists it as compatible with concentrates.

The V3 is the newest design. It is lighter, adds a percolator, a universal 14mm adapter and a built-in NFC chip for registration and authentication, and comes in Black, Desert Rose, Olive Green and Violet Purple. The Classic is the original 16-inch model, and its listing includes a silicone hose, infusion chamber, cleaning kit and a 10-year warranty on registration.

The Kompact uses the same 360° rotating system in an 11-inch frame instead of the Classic’s 16 inches, and it adds a tray and a luxury travel case. It suits smaller spaces and taking the unit on the road.

No. Every Stündenglass works on its own with a standard 14mm bowl. The Modül is an electronic add-on with dry herb and concentrate tanks, a 320–430°F temperature dial and a 6,000mAh battery, so you can vaporize instead of using a flame. Whether it is worth adding depends on how you plan to use your unit.

Use isopropyl alcohol only, because other cleaners can damage the finish. For a quick clean, drain the water, add about ½ to 1 inch of isopropyl alcohol, reattach the top globe, rotate several times, then drain and rinse. Also clean inside the valve by removing the magnetic bowl adapter end cap and rubber plug. The glass globes are the only parts that are dishwasher safe.

Buildup on the internal valve seals is almost always the cause. Clean it right away with the quick-clean method. If buildup is left too long, the seals can tear and need replacing; replacement seals come in the Stündenglass maintenance kit.

Unthread the top globe counterclockwise and pour water through the drain hole in the body until it reaches the top of the visible glass. Reattach the top globe clockwise until snug. Never remove the bottom globe while the unit is holding water.

Warranty depends on the model. City Vaporizer’s listings show a 10-year warranty on registration for the Classic, Kompact and the Grateful Dead, Tyson and Khalifa editions, and a 1-year warranty (2 years upon registration) for the V3. Register your unit with Stündenglass to activate the longer coverage. City Vaporizer is an authorized reseller, so the full manufacturer warranty applies.

Stündenglass was founded in 2012 by inventor Tracey Huston. Grenco Science, the company behind G Pen, acquired Stündenglass in 2020, and the brand is now part of the Grenco family.

Besides dry herb, the listings describe it as multipurpose for hookah, mixology, culinary use and aromatherapy. The V3 page also mentions a Beverage Smoking Cap for infusing drinks.
