TAG - Closed End 28/18MM Double UFO Downstem
TAG – 28/18MM Super Slit Double UFO Downstem
Dual Diffusion. Smooth Pull. Advanced Function.
The TAG 28/18MM Super Slit Double UFO Downstem is built for performance and airflow.
Featuring two stacked UFO-style diffusers, each lined with multiple super slit openings, this system provides heavy, even diffusion without restricting draw speed. The 28MM male outer joint fits large-joint beakers and straight tubes, while the 18MM female inner joint maintains compatibility with standard 18MM male slides.
Key Features
-
🛸 Dual UFO Diffusion Chambers – Two stacked UFO percs deliver layered bubble action for smoother, cooler draws.
-
💨 Super Slit Design – Each diffuser features high-density slits for maximum surface agitation and balanced resistance.
-
⚙️ 28/18MM Joint Configuration – Large outer joint (28MM male) connects to 28MM beakers; inner joint (18MM female) accepts 18MM slides or accessories.
-
🧱 Thick Borosilicate Construction – Durable, precision-ground joints ensure a snug, airtight seal.
-
🧼 Open Flow Design – Clears easily with minimal splash and smooth drag reduction.
Downstem Measurement Note
Downstem length is measured by insert length (from the end of the frosted joint to the tip).
Always confirm your existing fitment before purchase.
