Collection: Downstems

A down stem is a long tube that is inserted into the bong
and extends down into the water chamber. It is used to channel smoke from the
cone piece into the water chamber, where it is filtered and cooled before being
inhaled.

Length:

Down stems come in different lengths to fit different bongs, so it's important to choose one that is the right length for
your bong.

 Joint size:

Down stems also come in different joint sizes so it's important to choose one that is the right size for your bong.

There is 2 sizes on any down stem, the outer joint which is the size that fits your bong, and the inner joint which is the part that holds your cone. The outer joint is always listed first.

Material:

Downstems can be made of several materials, but some of the most popular types are metal downstems, silicone downstems and glass downstems.

Cleaning:

Regular cleaning of the downstem is important to keep the bong in good working order.
