This is for a fully assembled Rapid Star head, which includes the octagon, nozzle holders, teflon ring, spring, mating gear and axle. It also comes with all the necessary hardware to mount the axle (M6 nut and M2 screws) and tube fittings.
NOTE: We strongly recommend to not dis-assemble the axle from the star. There is risk of scratching the teflon ring if the axle is not re-assembled with care. Any scratches can therefore cause the teflon ring to leak air. If you do need to dis-assemble and re-assemble the axle for any reason, please do so with care. The teflon ring is a consumable and may need to be replaced from time to time during maintenance. Replacement teflon rings sold separately here. Do NOT add any lubricants to the axle, teflon is a natural lubricant. Adding any lubrication will end up clogging the airflow.
