Clear, laboratory-grade, American-made scientific glass. That's what you can expect from Grav Labs bongs, pipes, handheld bubblers, spare parts and accessories! Based in Austin, Texas, Grav Labs offers handmade quality and craftsmanship, resulting in the durability and solid, sturdy feel we love about American glass pieces produced in low volume.

Grav Labs is known for their innovative range of Helix Pipes and bongs. Utilizing Bernoulli's principle of airflow in a Venturi shape, Grav Labs' Helix pipes feature pinholes in the shoulders of the chamber, all angled in the same direction to produce an aeration process that slows burning, cools and smoothes smoke, and creates a swirling vortex that's fun to watch! The Helix smoke-cooling technology is available in a whole line of glass hand pipes and even bongs and precoolers.

For spare and replacement parts, or to upgrade or add to your bong set-up, don't miss Grav Labs bong accessories! Try a slide bowl with a built-in glass screen, a showerhead downstem, or even a concentrate nail head attachment for smoking oil with your Helix Multi Pipe!
