If you've ever bought a new downstem for your bong only to find out it doesn’t fit—yeah, we feel your pain. A downstem that’s too long can hit the bottom and block airflow, while one that’s too short won’t diffuse your smoke properly. And let’s not even talk about getting the wrong joint size—because nobody wants to deal with a wobbly, leaking setup.
So, how do you avoid all this frustration? You measure your downstem correctly before buying a new one. And lucky for you, we’ve got an easy step-by-step guide to make sure you get the perfect fit.
What is a Downstem, and Why is It Important?
Before we start measuring, let’s get one thing straight: the downstem is the unsung hero of your bong. It’s that glass tube that connects your bowl to the water chamber, filtering and cooling your smoke for a smoother hit.
Think of it like a straw—except instead of sipping a drink, you’re pulling cool, filtered smoke into your lungs. If the straw is too long, it hits the bottom of the cup. Too short? You’re barely getting anything. That’s why the right downstem size is crucial!
Tools You’ll Need
Measuring a downstem doesn’t require fancy equipment. You just need:
✔ A ruler or measuring tape – Because we’re actually doing this right.
✔ A pencil, straw, or chopstick – Trust us, you’ll see why in a second.
✔ Your bong – Obviously.
✔ A dime (optional) – More on this later.
Now, let’s get to the fun part.
Step 1: Measuring the Downstem Length
-
Insert the Pencil Trick
- Grab a pencil, chopstick, or straw, and gently place it into the female joint (the opening where your downstem goes).
- Push it down until it’s about half an inch from the bottom of your bong. Why? Because if the downstem touches the base, it might block airflow or even break.
-
Mark It!
- Use your finger or a marker to mark where the pencil meets the opening of the joint.
- Make sure you’re measuring from the part that sits inside—not the extra length sticking out.
-
Measure That Mark
- Take out the pencil and use a ruler or measuring tape to check the length from the tip to your mark.
- Boom! That’s your downstem length.
Step 2: Finding the Joint Size
Now that you know the length, let’s figure out what size joint you need. Downstems typically come in 10mm, 14mm, or 18mm sizes.
How to Check Your Bong’s Joint Size:
✅ The Dime Trick:
- Take a dime and place it over the bong’s female joint.
- If the dime fits inside the joint, congratulations—you’ve got an 18mm joint.
- If the dime sits on top, it’s 14mm or smaller (keep reading to narrow it down).
✅ The Pencil Test:
- Stick a regular pencil inside the joint.
- If it fits snugly, the joint is probably 14mm.
- If there’s still a gap, it’s 10mm.
Still not sure? Most standard bongs use 14mm joints, but always double-check before ordering!
