High-airflow design keeps the draw open through water.
Two adapters per pack, because glass breaks.

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 joint into your water pipe.

Soak in isopropyl alcohol, rinse with warm water and dry fully. Use the spare in the meantime.

I’ve been using this adapter almost daily with different water pieces and it’s been rock solid. The fact it fits 10mm, 14mm and 18mm without swapping parts is super convenient. Airflow is excellent and doesn’t choke the Solo at all. I definitely recommend using concave screens, but I tested it with flat ones too and they stay put once pushed in. Thick glass and feels like it’ll last.
I mainly got this for the Solo 3 and it fits perfectly. Pulls are wide open and smooth through water. I got the concave screens and I'm glad I did!
Really good airflow and fits all my glass without issues. Glass feels thick and durable, much better than cheaper adapters I’ve tried.
This is honestly the best water adapter I’ve tried for my Solo 3. Super fast airflow and no fiddling with extra adapters.
Great products and quality. Thicker glass than the original ones.
Does exactly what it should. I use concave screens but you can poke in a normal one if needed. No restriction on airflow.
Works great and airflow is strong

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.
Most water pipes use a 10mm, 14mm or 18mm female joint. Our guide on choosing the right joint size shows how to tell.
Both have the stepped 10/14/18mm joint and high airflow. The Aero XL WPA adds a deep-fill chamber for bigger loads.
They're optional. Some customers use concave screens for the most open airflow, or a standard domed screen.
Soak it in isopropyl alcohol, then rinse thoroughly with warm water. Let it dry fully before use. Our stem cleaning guide has more tips.
