5" Downstem

Connecting the bowl to the water chamber, the downstem provides suction to pull smoke through a bong or dab rig, causing the water to bubble in the main chamber. Smoke or vapor is then inhaled by the consumer.

Downstems can be affixed to the bong or dab rig or be removable. They come in different sizes, usually 10mm, 12mm, or 14mm in thickness. You need the proper size to create an airtight seal between the bowl or nail and the main chamber, otherwise you won’t be able to draw smoke properly.
