Classic Design. Stronger Build. More Chug.

The TAG Open End 4 Slit Showerhead Downstem is a simplified version of the classic TAG showerhead design. By using fewer slits, this version prioritizes durability and a more traditional, chuggy draw while still providing reliable diffusion.

The open-end layout allows full airflow when clearing a hit and helps debris pass through the stem rather than collecting inside it.


Key Features

💨 4 Slit Showerhead Diffuser
Reduced slit count creates a stronger pull and more pronounced chug compared to higher-density showerheads.

🔧 Durable Slit Layout
Fewer openings mean thicker glass between cuts, increasing overall strength and longevity.

🌬 Open-End Design
Allows unrestricted airflow during clears and helps prevent clogging by letting debris exit the stem.

⚙️ 18/14MM Joint System
Fits standard 18MM female joints and accepts 14MM male slides.

🧱 Borosilicate Glass Construction
Designed for everyday durability and reliable performance.


This downstem keeps the familiar TAG showerhead function while leaning toward a sturdier, more classic feel. It is a solid choice for users who prefer stronger pulls and long-term durability over ultra-fine diffusion.
