This “Swirly Ball” carb cap is made of clear glass and is specifically designed for use with the quartz Thermal Bangers that we received from High-Man Glass.
Swirly Ball Carb Cap
The Swirly Ball carb cap is a popular choice and extends most of the way to the bottom of the dish. This cap will direct the airflow to about 2 millimeteres above the bottom of the concentrate dish.
If you like to add a lot of concentrate to your dish at once the swirly ball carb cap may actually blow the liquid around in the dish while in use, so be careful!
