🔍 What Is a Downstem & Why It Matters

A downstem is a key piece of any bong setup. It connects your bowl to the water chamber, allowing smoke to travel through water for filtration. Choosing a glass downstem ensures a pure-tasting, cool hit — no plastic or metal flavors here.

🧠 How to Measure Your Bong for the Right Downstem

Not sure if this stem fits? Here’s an easy test:

• Use a dime. If the joint is the size of a dime, it’s 14mm.
• If a dime slides into the joint, it’s 18mm.
• Smaller than a dime? You’ve got a 9mm joint.

✅ This downstem is 18mm to 14mm, meaning it fits an 18mm joint and holds a 14mm bowl.
