Metal instead of glass
A stainless steel body stands up to pocket carry better than a glass stem.

Fast cooling
The metal balls take heat out of the vapour inside a slim stem.
A spare included
Two stems, so one can be cleaned while you use the other.
Fit it to a cool tip
Push the stem onto your DynaVap tip while the tip is cool, until it sits firmly.
Heat as usual
Load the tip, heat the cap until it clicks, then draw.
Mind the heat
The steel balls hold heat, so let the stem cool before you take it off the tip.
Clean the balls
Soak the stem in isopropyl alcohol, rinse with warm water and dry it fully.

Review of Long Glass Mouthpiece for VENTY
★★★★★Green GidroVerified buyerCool stuff
Loving my sessions with this glass mouthpiece! The beads inside make a real difference, the vapor is noticeably smoother and cooler. It looks great too. Next step: I’m definitely ordering the stainless steel bead version to test and compare!

Review of Long Glass Mouthpiece for VENTY
★★★★★Peter ReidVerified buyerSO much smoother on your throat!
This mouthpiece is brilliant, almost as good as a bubbler without the small hassle of adding water etc. Other than my glass bubbler it’s the first glass mouthpiece I’ve used. Going to order a 2nd one to rotate them so they’re kept clean

Review of Vibrant Beads Stem for POTV
★★★★★RipVerified buyerI love this stem
I love this stem, it cools the vapor. It’s great for one session, gets a little warm when you do two sessions in a row but way cooler than the POTV stem. Well worth the money.

Review of Vibrant Bead Stem for TinyMight
★★★★★Zachary FreemanVerified buyerI like this straight stem, it’s purty!
I like this straight stem, it’s purty! Maybe a version that’s shorter would be nice. What I want to know is exactly how many glass bb’s are in the tube?

Review of Slim Beads Stem for POTV
★★★★★stacieVerified buyerGood but the stainless steel is better
Will it fit my DynaVap tip?
It is made for standard DynaVap tips: the M 7, M 7 XL and earlier M tips. Not the UniDyn, whose tip and stem are one piece. See the compatibility list.
How do I clean it?
Soak it in isopropyl alcohol, then rinse thoroughly with warm water and let it dry fully before use. See our guide to cleaning DynaVap glass.
Is this an official DynaVap part?
No. The Steel Beads Stem is made by The Vapetrix to fit DynaVap tips. It isn't made or sold by DynaVap.
Is it glass?
No. The body and the balls are stainless steel. If you want glass, see the Slim Beads Stem or the full comparison.
Glass or metal: which cools more?
Read our guide to metal and glass DynaVap stems. For the most glass surface in a dry stem, see the Large Beads Stem.
