Downstems

Downstems function to carry smoke from the slide (or bowl piece) into the water chamber of your glass pipe to filter and cool each hit. Downstems are available in a variety of different sizes and lengths, so it is absolutely essential to know what you need before purchasing one.

When buying a new downstem, you’ll need to know two things: joint size and length. These are the two standard measurements that headshops use when selling. Downstem sizes come the same way joint sizes do, in the standard sizes of 14mm, 18mm, and the less common 10mm for mini dab rigs.

When measuring the length of your downstem, make sure to start at the very bottom of the sandblasted segment and continue to the end, past the diffuser. If you measure the entire length of the glass accessory, you will get an inaccurate length and may purchase an incompatible downstem.
