Glass Downstems FAQ

What is a glass downstem?

A glass downstem is a hollow tube that connects your bong’s bowl to its water chamber. It channels smoke through the water, helping cool it and filter out impurities.

How do I choose the right size glass downstem?

Measure the joint size (usually 14mm or 18mm) and the length from the bottom of the joint to the base of the water chamber. Length is typically measured in millimetres or centimetres.

What’s the difference between a diffuser downstem and a standard downstem?

Diffuser downstems feature slits or holes at the bottom to break smoke into bubbles, providing better filtration and smoother hits compared to straight, non-diffusing stems.

Are glass downstems easy to clean?

Yes — soak them in isopropyl alcohol and rinse with warm water, or use a bong cleaning solution. Glass is resistant to heat and resin, making it easy to maintain.

Can I use a coloured glass downstem with any bong?

As long as the joint size and length match your bong, you can use any coloured downstem to upgrade your look without sacrificing function.
