The quartz Halo is the orignal cold worked quartz dish, and the Nimbus is its successor.
The nimbus is over 70% greater dish capacity than Halo dishes, high polish exterior, and tooled interior for increased surface area and capillary action.
Compatible with all slim and s-series base/lug assemblies, all Halo caps.
28mm barrel heater is recommended for increased contact.
NOTE: Slim series 14mm male joints also function as 10mm female joints.
