Fat Clear Kinky Inline Downstem — ZongGlass Borosilicate.

The Fat Clear Kinky Inline Downstem is a hand-blown borosilicate glass downstem from ZongGlass, designed for use with ZongGlass bongs and compatible glass-on-glass setups. Made at the ZongGlass workshop in Phoenix, Arizona by the same team that has been producing Zong bongs since 1992. Every downstem is made to order from durable borosilicate glass.

Borosilicate Glass

ZongGlass downstems are made from the same borosilicate glass used throughout the ZongGlass range. Heat-resistant, chemically inert, and built to last through regular daily use. The borosilicate material handles thermal stress without cracking the way thinner soft glass does, which matters on a component that sees direct contact with hot smoke every session.

Glass-on-Glass Compatibility

The Fat Clear Kinky Inline Downstem uses a standard glass-on-glass joint for a sealed, airtight fit with ZongGlass bongs and other compatible setups. The ground glass seal eliminates the airtight issues that come with rubber grommets and keeps the vapour path clean.

Made by the Original Zong Team Since 1992.

Every Fat Clear Kinky Inline Downstem is made to order at the ZongGlass workshop in Phoenix, Arizona. Standard lead time 2–3 weeks; up to 30 days at peak.
