These serve as a replacement glass airflow cap for your V4 Crucible Atomizer, built in to the top is a 14mm male water tool adapter for easy compatibility with hydrotubes such as the Hubble Bubble. This part removes all the metal from the top of your setup creating a glass only air path and also stays significantly cooler than the original metal cap.
Please apply o-ring lubricant or vegetable oil to your o-rings before installing this cap to reduce forces and it possible use the green viton o-rings. We are not fit testing them all anymore as we had a complaint that one arrived greasy due to the lubricant on our o-rings. We suggest using them with the bottom atomizer o-ring removed to reduce the resistance making them less likely to be broken.
Glass V4 Crucible replacement airflow cap

These are handmade glass so there is a little variation in manufacture. We visually check all these caps on arrival to ensure they should function well. Tube intake height varies slightly between them. We line them up to visually checking them but this is not a perfect method so please let us know if you receive one which doesn't work well.
This listing is for the Airflow cap only, it does not include other parts displayed in images.
