This glass ball cap works very well on the Jcvap 5D XXL chamber and is a perfect fit. There are two options available: one with a silicone cap and one with only the glass ball cap. If you have purchased our complete chamber set and only need to replace the ball cap, you can buy just the ball cap. If you are using it for the first time or need to replace the existing silicone, we recommend buying the one with the silicone cap.

Please note: this product does not fit other third-party products. Do not use it with other devices.
