Tree Perc

One of the most recognized and popular percolators around is the Tree Perc. That’s why Grav Labs knew they had to create a Tree Stax. This interchangeable perc features eight arms with two vertical slits on each arm. With a design like this you get maximum diffusion with minimal drag. Since every Stax piece comes apart you can clean every inch with ease. We recommend using Grav joint clips when attaching any Stax pieces together.

Product Details:

  • Height: 6-1/2''
  • 45 x 5mm Borosilicate Glass Tubing
  • Attaches to any Stax Mouthpiece, Perc or Base
