Downstems

Downstems are another opportunity to add extra filtration to your glass bong or bubbler. Downstems act as a second or third percolator depending on your setup. Acting as the bridge between your bowl and bong or bubbler, downstems are often matched with their bowls or colour scheme of the glass piece. When looking for a downstem it is important to measure your current stem to make sure a new one will fit. After that, you want to make sure you have the right size opening for your bowl, whether it is 14mm or 19mm. 

Downstems usually come unbranded. However, if you are looking for replacement stems for a Shatter'd Glassworks piece, you can find them here.
