A bong bowl (also known as a slide) is an essential part of every bong or water pipe. These pieces sit within the joint of your water pipe and serve one important purpose: to hold the tobacco, loose leaf herb, or legal dry herb.
Bowls come in a variety of different sizes (10mm, 14mm, and 18mm) and can be either male or female. Knowing the joint size and gender of your water pipe is essential when purchasing a new slide, otherwise you may end up with a new bowl that is not compatible with your bong!
