Grav Glycerin Chiller Attatchment (19mm Green)

The 19mm GRAV® Chiller Attachment is 5" tall and filled with glycerin that can reach sub-zero temperatures without freezing. Its central coil maximizes the surface area to which airflow is exposed, cooling smoke or vapor before it enters a water pipe. The chiller features 19mm male and female joints at either end, making it compatible with any 19mm water pipe and accessory.
