The large GRAV® Circuit™ Rig is 7" tall and made with 60mm thick glass tubing. Its intake hole is set into the body of the rig at an angle, creating a rapid spin and powerful centrifugal force, and its twin chambers are stacked to double the Circuit™ percolator effect.
The vapor is cooled and filtered by the speed and force of the water while a sharp bend in the mouthpiece prevents water from exiting the rig. The large Circuit™ comes ready to use with a 14mm female-jointed domeless nail made of heat-tolerant quartz.
