The stepped, frosted joint connects to 10mm, 14mm and 18mm female joints.
The deep-fill chamber holds more than a standard adapter stem.
High airflow for open pulls, and around 25% thicker glass for everyday use.

Your water pipe needs a female joint of 10mm, 14mm or 18mm.

Fill the chamber end, with a domed screen if you like.

Insert the chamber end into your device and the frosted joint into your water pipe.

Soak in isopropyl alcohol, rinse with warm water and dry fully. Use the spare in the meantime.
Water pipe and Arizer device not included.

Great airflow, and the and with a medium grind herb, you don't even need the screens! My Solo 3 my water piece, worked together so much better!
The folks at VapeTrix are fantastic in that they have great products, very competitive prices, and pretty fast shipping. No hassles at all. I've ordered twice from them with great experience both times. I'd gladly recommend them for anyone with an Arizer Solo 3 v2 looking for accessories. They have a great team.
These are simply awesome. The added airflow makes it alot easier to fill up the stems since you can now pack them tighter and still have enough airflow for vaping. The glass is thicker than the original stems so they seems more sturdy also.
These are amazing! Super deep fill and an open airway make for beautifully easy clouds! Pair with a glass star filter and preheat slightly for optimal vapour production Fits Solo and Air perfectly.
No issue with the quality of the products. Customer service is difficult to deal with. They simply ignore multiple requests for information
Great products, well packed and great service. Very good experience from this company.
Good product. Great service. The only place I purchase my add on glass.
Perfect perfet perfect
Great airflow.
Good product, the high airflow is nice, but one of my WPA's has a small crack in it, but it doesn't seem to impact performance
Great addon for the solo 3. Only problem is I just need the 18mm joint and the 10mm does bottle neck the Airflow a bit.
The glass on these is certainly thick. The OEM WPA from Arizer has an OD of 14.5mm. The two tubes I just received from vaptrix are 14.56mm and 14.61mm, which makes them a little tight to get into and out of the solo3. The inner dimension (ID) of the original WPA is 11.45mm. The ID of the Vaptrix tubes are 10.25mm and 10.4mm for the two tubes. Proof the glass is thicker, but that is problematic for me. The OD being larger makes getting them in or out more difficult, but certainly not impossible. The smaller ID means no dosing caps. If you are ok with these limitations, these are good WPAs. I was hoping to use with dosing caps, but mine don’t fit.

To use your Solo or Air with a water pipe, yes. The adapter takes the place of your stem: load it, insert it into the device, and connect the joint to your water pipe. Read do you really need a water pipe adapter?
10mm, 14mm and 18mm female joints. The stepped male joint covers all three, so one adapter works with most water pipes and bubblers.
Most water pipes use a 10mm, 14mm or 18mm female joint. Our guide on choosing the right joint size shows how to tell.
The Aero XL WPA covers 10mm, 14mm and 18mm joints and adds an XL chamber and high airflow. The 14mm WPA is a simpler adapter for 14mm joints only.
Yes. It's made for the Solo 2 and Solo 2 MAX, and the rest of the Solo and Air series.
Soak it in isopropyl alcohol, then rinse thoroughly with warm water. Let it dry fully before use. Our stem cleaning guide has more tips.
