FAQs about Downstems

What is a downstem and why is it important?

A downstem is a cylindrical piece that connects your bowl to the water chamber of your bong. It draws smoke into the water for cooling and filtration, making each hit smoother and less harsh.

What sizes of downstems are available?

We stock all major joint sizes: 14mm and 18mm. Lengths range from 8cm to 17cm to fit most straight tube and beaker bongs.

What’s the difference between diffused and non-diffused downstems?

Diffused downstems have slits or holes at the base that break smoke into smaller bubbles, increasing surface area for better cooling and filtration. Standard downstems have a single open end and offer more direct airflow

Are glass or metal downstems better?

Glass downstems offer better flavour and smoother hits, but are more fragile. Metal downstems are nearly unbreakable, making them ideal for travel or frequent use. Both have their advantages—it depends on your needs.

How do I clean a downstem?

Soak your downstem in isopropyl alcohol with coarse salt, shake gently, and rinse with warm water. For metal options, you can also use boiling water or pipe cleaners for deep cleaning.

Can I use a metal downstem on a glass bong?

Yes—as long as the joint size matches, metal downstems can be used in both glass and acrylic bongs. They’re especially handy for grommet bongs that use rubber seals.
