130mm of glass and over 100 small beads give vapour lots of surface to cool against before it reaches you.
Cooler draws with no bubbler to fill, empty or spill.
The stock POTV stems are short. This one is much longer and packed with beads.

Pull your current glass stem straight up and out of the top of your LOBO or ONE. With the stem out, it's a good time to fit a fresh brass screen.

Push this stem straight down into the same opening on top until it sits snugly. No twisting needed.

Set your temperature as usual and draw slowly.

Soak in isopropyl alcohol, rinse with warm water and let it dry fully before refitting.
Your POTV device is not included.

Review of Ultra Cooling Beads (2-pack)
I really enjoyed this product. It has come in handy on several occasions.
Review of Dimpled Stem (2-pack)
Love it! The glass stems arrived in perfect condition and are great for the price, and the green looks amazing with my green potv lobo vape.
Review of Globe Stem (2-pack)
The attachment works great it seems fine, I like it a lot. Cleans up easily
Review of Dimpled Stem (2-pack)
Perfect fit in my POTV Lobo. Ordered this because POTV suspended international orders.
Review of Ultra Cooling Beads (2-pack)
100% improvement. Way better than the stock stem.
Review of Spiralled Stem (2-pack)
Really love it, just fun to use
Review of Ultra Cooling Beads (2-pack)
Out of all the glass attachments i have tried for my POTV mighty+ adapter, this is BY FAR THE EASIEST TO CLEAN!!!!!!! Literally just put ipa in there and shake it for like 10 seconds.
Review of Dimpled Stem (2-pack)
It’s quite a bit longer than the original equipment but it works great. I’ve had it for a couple of weeks and it’s still good as new. It’s made from glass so it’s not indestructible but it’s held up fine with my highly active lifestyle.
Review of Slim Steel Beads (2-pack)
These are now my favorite
Review of Slim Vibrant Beads
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 Bubbler Stem
Didn't expect this much cooling from such a small bubbler. Easy to use, cleans fast, and feels well balanced on the device.
Review of Bubbler Stem
Fits insanely tight on my LOBO, zero wobble at all. Feels really secure and the cooling is excellent. Glass quality feels solid.
This one is longer (130mm) with lots of small beads in one stem. The Ultra Cooling Beads has larger beads in a wide chamber and comes as a pack of two. See the comparison.
Yes. At 130mm it's much longer than the stem that comes with the Lobo or ONE, which is what gives the extra cooling. It sticks out further, so it's best for home use.
Soak the whole stem in isopropyl alcohol and give it a gentle shake so it reaches between the beads. Rinse well with warm water and let it dry fully. Don't push brushes into the beads. More in our bead stem cleaning guide.
Yes. It's made for the Planet of the Vapes Lobo and ONE and fits the same way on both. See the Made for tab.
Yes, the POTV XMAX V3 Pro with its POTV Accessory Attachment. For a standard XMAX V3 Pro or V4 Pro, see the Made for tab.
Yes. Keep a screen in your Lobo or ONE so loose material can't get into the stem. Our 9.8mm brass screens are made for the Lobo.
The Lobo runs from 160 to 221°C. Start low for flavour and work up in small steps; a cooling stem keeps higher settings smoother. See our best temperature ranges for the Lobo.
