This 14.5" Dab Rig Is not like any other rig in our store. This piece has a straight tube design. Once you inhale, this piece provides your product with 4 separate chances for filtration. Ensuring a SMOOTH rip. The first stop on your product's journey is the barrel percolator at the bottom. This thing makes for some nice function and even better filtration. The next stop is through the TRIPLE DISC Percs! These act as another bit of diffusion and stop the water from quickly going back to the bottom of the piece. It comes with a 14mm Male banger, but if concentrates are not for you, you can always replace grab another 14mm male bowl from our store, and this piece will be able to do whatever you need it to!
