TAG - 18" Beaker Bong 50x9MM - 28/18MM Matrix Downstem (4.50")
TAG – 18" Beaker 50x9MM – 28/18MM Matrix Downstem
Upgraded System. Larger Joint. Smoother Diffusion.
Built from 50×9MM borosilicate glass, this 18-inch TAG Beaker features TAG’s 28MM joint system, designed for maximum airflow, durability, and cleaning access.
The included Matrix Super Slit Downstem provides exceptional diffusion with smooth, consistent airflow — delivering a top-tier beaker experience with premium function and feel.
Key Features
-
💨 Matrix Super Slit Downstem – Dense slit array maximizes diffusion efficiency while keeping airflow free and easy for fast, clean clears.
-
🔒 28MM Super Thick Female Joint – Reinforced for strength and performance. Note: 28MM joints are currently unkeckable — no available Keck Clip fits TAG’s 28MM Super Thick joint size.
-
🧱 50×9MM Borosilicate Glass – Ultra-thick glass for outstanding strength and weighty stability.
-
🔥 Pinched Screen Handle Slide (Included) – Three precision pinches form built-in holes that prevent pull-through while maintaining steady airflow.
-
❄️ Ice Pinches – Allow stacking ice for cooler, smoother draws.
-
⚙️ Chamfered Beaker Edge – TAG’s signature beveled base design enhances visual appeal and helps resist edge chipping from tip-overs.
28MM System Advantages
The larger 28MM joint isn’t just for size — it’s an upgraded diffusion platform.
It allows for more advanced downstem styles like TAG’s Matrix or Double UFO Super Slit designs, improving both function and cleaning convenience.
The wider joint also makes it easy to drop ice directly into the beaker base and access the interior for maintenance.
Prefer using 18MM downstems instead?
You can easily adapt with the TAG Compact Adapter (28MM Male to 18MM Female):

Why You’ll Love It
This beaker is all about power, performance, and precision.
The 28MM system delivers superior airflow and cleaning access, while the Matrix diffusion provides buttery-smooth function.
With its 9MM-thick walls, heavy base, and upgraded joint, this piece sets the bar for durability and long-term reliability — a true high-end daily driver.
