In the case of replacing or upgrading elements of your bong, not many accessories can have a greater impact than a good downstem. This is a very important, but underestimated aspect that contributes so much to the smoothness and flavor of each puff and the satisfaction of taking them. A downstem is a key component in the smoking process whether you are starting out, and you want to optimise your set-up, or a full-scale smoker and you need something to filter better.
How about breaking it down? And accordingly helping you to choose the best downstem to fit your bong.
What Is a Downstem and Why Does It Matter?
The downstem is the tube that connects the bowl (where your herb sits) to the base of the bong. It carries smoke into the water, allowing it to cool and filter before you inhale. A good downstem doesn’t just do the job, it enhances the overall experience.
Without the right fit or length, your bong might not percolate properly, leading to harsher hits and wasted smoke. That’s why knowing what to look for is key.
1. Check the Joint Size of Your Bong
Bongs typically come with joint sizes of 14mm or 19mm, and choosing the wrong size downstem will result in a poor fit or no fit at all. Make sure to measure your bong’s joint or check its specs before shopping.
Top Pick:
14mm Female Downstem – Ideal for standard bongs, this piece offers a perfect seal and airflow for consistent, satisfying hits.
2. Measure the Length You Need
Downstems come in various lengths, usually ranging from 3 to 6 inches. To find the right size:
- Remove your current downstem.
- Measure from the bottom of the joint to the tip of the submerged end.
If the downstem is too short, it won’t reach the water. Too long, and it might not fit in the chamber.
Top Picks:
6 Inch 14mm Female Downstem – Great for larger bongs with deeper chambers.
5 Inch Glass Downstem – A versatile size that fits many mid-sized bongs.
3. Choose Between Fixed and Removable Downstems
While some modern bongs come with fixed downstems, many prefer removable ones because they’re easier to clean and replace. If your bong uses a removable downstem, you have more freedom to upgrade.
A clean downstem makes a huge difference in taste and draw. If yours is clogged or stained beyond help, it’s time for a new one.
4. Look for Quality Materials and Design
Always choose a borosilicate glass downstem it’s heat-resistant, durable, and designed for repeated use. Also, check for precision slits or diffusers at the bottom of the downstem. These small cuts break smoke into tiny bubbles for smoother hits.
Top Pick:
19mm Female Glass Downstem – A sturdy, reliable option for larger bongs with 19mm joints.
5. Think About Percolation Style
Some downstems come with built-in percs or slits for better diffusion. These options are ideal if you want a smoother, cooler smoke. If you prefer a raw, more direct experience, go for a simple open-ended downstem.
Upgrading your downstem is one of the easiest and most effective ways to level up your smoking setup. It’s all about the right size, the right fit, and the right performance.
