These are replacement airflow caps for the Quartz Quest NE and SiC Quest by Divine Tribe.
Available with the original single airflow cap or with the Vortex airflow and 14mm male water tool adapter cap. Please select from the menu.
Regular Caps - 1 x Regular Single Airflow Cap
Vortex Caps - 1 x Dual airflow cap with 14mm male water tool adapter, includes 2 spare o-rings.
If the airflow tube sits a little low and makes contact with your bucket, please use one o-ring as a spacer, placing it on the atomizer base so that the airflow cap cannot be pushed all the way down as shown in the last photo.
