Downstems
A downstem is a tube, usually made from glass, which runs down into the chamber of your bong. The downstem connects to an outer stem, which is typically part of your bowl piece.
Your downstem is essential for transferring smoke from your bowl into your bong. Without a downstem, your bong will be effectively useless!
Because your bowl and downstem need to connect with an air-tight seal, it’s important to get a downstem which is compatible with your bong and bowl piece.
All of our downstems and bowl pieces are measured in millimeters (mm). Be sure to check the size of your glassware before ordering to ensure you’re purchasing compatible parts.
