TAG - 28/18MM Matrix Bong Downstem
TAG – 28/18MM Super Slit Matrix Downstem
Matrix Precision. Maximum Airflow. Premium Function.
The TAG 28/18MM Super Slit Matrix Downstem is engineered for high-performance diffusion.
Featuring a matrix grid of fine super slit openings arranged in multiple rows, this design provides exceptional airflow balance with dense bubble stacking and smooth, consistent draws. The larger 28MM male outer joint fits TAG’s wide-joint beakers and straight tubes, while the 18MM female inner joint maintains compatibility with standard 18MM male slides.
Key Features
-
🧩 Matrix Super Slit Design – High-density grid layout multiplies diffusion points for smoother, more refined airflow.
-
💨 Open Flow Function – Provides rapid clear while maintaining maximum bubble saturation and smooth resistance.
-
⚙️ 28/18MM Joint Configuration – Large 28MM male joint connects to TAG 28MM beakers; accepts 18MM male slides or adapters.
-
🧱 Thick Borosilicate Glass – Durable, precision-ground joints ensure airtight performance.
-
💎 Premium Feel – Engineered for both function and balance, with a polished scientific aesthetic.
Downstem Measurement Note
All TAG downstems are measured by insert length (from the end of the frosted joint to the tip).

Why You’ll Love It
The Super Slit Matrix Downstem is designed for users who want the perfect mix of performance and refinement.
