TAG - 30" Beaker Bong 80x7MM - 28/18MM Downstem (7.00")

TAG – 30" Beaker 80×7MM – 28/18MM Downstem

Massive Scale. Precision Engineering. Unmatched Presence.

The TAG 30" Beaker is a true showcase of large-format scientific glass.
Built from heavy 7MM borosilicate with an enormous 80MM body diameter, it combines monumental size with precision airflow. Despite its size, a reducing mouthpiece transitions the 80MM bore down to a traditional 50MM opening for comfort and usability. This beaker isn’t just large — it’s engineered for smooth, balanced performance at scale.

Key Features

• 🧱 80×7MM Borosilicate Construction – Massive, thick-walled tubing offers exceptional durability and visual impact.

• 💨 28/18MM Removable Downstem System – Large joint design supports advanced diffuser options and high airflow.

• 🔻 Reducing Mouthpiece Design – Smoothly narrows from 80MM to 50MM for a comfortable seal and natural feel.

• 🧊 Reinforced Heavy Base – Wide, thick beaker bottom ensures balance and prevents tipping despite large water volume.

• 💪 Super Thick Joints – Designed to handle the stress of a tall, heavy build.

• ⚙️ Open, Easy Flow – Massive internal volume allows high diffusion capacity and smooth clearing performance.

Handling & Use Note

At over 2.5 feet tall, this beaker requires careful handling and both hands for safe movement. Clearing the entire chamber in one breath is a challenge even for experienced users — consider it a test of endurance and performance.

Downstem Fitment Note

TAG’s 28MM system uses a 28/18MM downstem for optimized airflow and compatibility with 18MM accessories.
Small variances in downstem length (±¼–½") are normal.
