18.5 Inch Glycerin Coil Percolator Bong | 14.5 mm

This 18.5 inch straight tube bong is made from 5 mm borosilicate glass, designed for durability and consistent use. The tall structure and reinforced base provide a stable and balanced setup.

 The 17-arm percolator delivers high levels of diffusion, breaking airflow into finer bubbles for more effective cooling. The glycerin-filled coil chamber can be pre-cooled to further reduce vapour temperature without increasing draw resistance.

 The straight tube design keeps airflow direct, while the detachable glycerin section allows for easier cleaning and storage. The overall layout supports consistent performance across regular use.
