GRAV Large Circuit Rig

GRAV Large Circuit Rig 

Get double the rotation with the GRAV Large Circuit Rig. The angle of the intake hole causes water and vapor to spin rapidly and form a powerful centrifugal force. This cools the vapor and makes each hit smoother, and the twin stacked chambers multiply this effect. There's no need to worry about splashback with the Large Circuit Rig, because the sharp bend in the mouthpiece keeps all water inside the rig. This piece includes a 14mm female-jointed domeless nail made of heat tolerant quartz, so all you have to do is add about 0.5" of water and then you can get right down to the fun stuff.

Quick Tip :

A percolator is a compartment within your piece that allows water to pass through, acting as a filtration system that filters the vapor so that the hits are cleaner and smoother. While percolators ultimately reduce the potency slightly through the filtration process, they are practically essential as without them, each dab hit would simply be way too harsh. 

There are various perc styles out there to choose from:

• Tree percolators are extremely popular, looking like a network of tree limbs, and due to their design, they offer exceptional filtration, but are a bit more fragile and tough to clean.
• Showerhead percolators are also high in demand, with a showerhead-like structure containing multiple holes which pull the smoke into a filtration chamber.
• Diffused downstem percolators improve airflow with a series of slits that face downward.
