Downstems
Bong Downstems
Shop replacement downstems at WiseVapor — glass downstems, diffused downstems, and showerhead downstems for water pipes and bongs. Find the right size for your joint and style.
Downstem sizing
Two measurements matter: length (so the slits sit just below the waterline) and joint size + gender (the connection to your bong and bowl). Common sizes: 14mm and 18mm joints, in male or female. Measure your existing downstem before ordering.
Diffused vs. plain downstems
Plain downstems are a simple tube. Diffused downstems have slits or holes at the bottom that break smoke into smaller bubbles, increasing filtration and cooling.
Frequently Asked Questions
How do I measure my downstem?
Measure from the bottom of the joint flare (the part that sits in the bong's joint) to the tip of the diffuser. Length is usually quoted in mm or inches.
What's the difference between diffused and showerhead downstems?
A diffused downstem has slits or holes for breaking up smoke. A showerhead downstem has more numerous, smaller holes arranged in a showerhead pattern for even finer diffusion.
