Downstem

Introduction

A downstream is a key component of water pipes and bongs.

This tube conducts smoke from the bowl down through the water before inhaling. Downstems provide initial filtration and cooling of the smoke.

Let’s examine how these handy accessories work.

What is a Downstem? 

A downstream is a small-diameter tube that fits into a bong or bubbler below the bowl/joint. It extends downward into the water chamber.

The bottom of the tube contains slits, holes or percolators to diffuse smoke into the water, optimizing filtration.

When you light the bowl, smoke travels down through the downstream, where it bubbles through the water.

This cools and filters the smoke before entering the main chamber en route to your lungs.

Quality down stems diffuse smoke thoroughly without adding draw resistance.

Downstems are typically made of durable glass or silicone.

They can be fixed or removable for easy cleaning. Some feature diffuser slits or percolators for enhanced performance.

Benefits of a Removable Downstem

 The advantages of a removable down stem include:

• Ability to disassemble for thorough cleaning.
• Can replace or upgrade if needed.
• Allows for customization and experimentation.
• Reduces the risk of breakage when separating pieces.
• Aids storage and travel.

Thanks to their simplicity and function, downstems are must-have accessories for optimized water pipes.
