DynaVap BB3 Pink Glass Stem

The BB3 Pink Stem is the glass midsection of DynaVap's BB3 vaporizer, sold on its own as a replacement or spare part. It's a stem-length piece of glass holding three blue glass beads that move around a series of divots along the inside walls, breaking up vapor as it passes through for a cooler, smoother pull. The bottom is tapered to a 10mm female fitting, and there's a small air port built into the design. On its own this stem doesn't do anything: it needs a Tip and Cap on top to become a working device, but paired with either the Titanium Tip or Stainless Steel Tip it completes a full BB3 setup in pink glass.

Glass is the appeal here: unlike the metal-stem DynaVap models, the BB3's midsection lets you watch the beads move and see buildup forming, which makes cleaning timing obvious in a way opaque stems don't. The tradeoff is durability. Glass can chip or crack if dropped on a hard floor, and DynaVap's shipping warranty only covers damage that shows up within 48 hours of delivery, so inspect the piece as soon as it arrives. A quick tip: rinse the stem with isopropyl alcohol and let the beads and divots soak for a few minutes rather than scrubbing, since the divots are where residue collects fastest. If pink isn't for you, the same stem also comes in Blue, and it works with the complete BB3 device or any Tip and Cap from the DynaVap collection.

Recommended if you want a splash of color in your BB3 build and like the idea of a glass stem you can see through, but pick a metal-stem DynaVap model instead if you're rough on gear or prone to dropping things.
