Downstems for Bongs are essential for connecting your bowl slide to your water pipe, filtering smoke through water for smoother, cooler hits. A downstem is typically measured from the bottom of the frosted joint to the tip, and most standard models convert an 18mm joint into a 14mm bowl fitting. We carry both 14mm downstems and 18mm downstems, so you can find the exact fit for your glass piece.

Looking to improve diffusion? Choose from slitted downstems, gridded downstems, or other diffused downstems for extra percolation. We also stock stylish wig wag and solid color downstems for unique style, as well as standard replacements to keep your bong functioning like new. No matter the size - 14mm, or 18mm - we’ve got every option covered, making us the best place to buy downstems online.
