The CNC hookah is machined in the United States from 6061-T6 aluminum. The overall length is 24.4” including the 7” downstem. The center section can be removed to shorten it to 17” including the downstem. The base of the stem is 1.56” wide giving you a wide range of glass bases to use. The hookahs have a high quality anodized finish to protect them for a lifetime. This finish also makes the hookah very easy to clean. They feature a large ⅜” stainless steel ball for the purge valve. We include a high temp silicone isolator to prevent the hookah stem from heating up.
