HVY Glass Downstems are replacement downstems for your HVY bong. These glass downstems are an original replacement. HVY downstems fit most standard bongs, bubblers, and water pipes requiring a 14/18mm fitting. The 14/18mm diffused downstems feature quality boro glass and several diffusion slits for added airflow and superior water filtration.
