The T3 is eGo Cone threaded and NOT 510 threaded. This clearomizer fastens onto the outer cone threads of an eGo battery. The T3s can only be used on a non-eGo battery if used with a 510 to eGo adapter.

• Unlike other Clearomizers, the mouthpiece of the T3s is permanently attached and it is filled from the bottom. This two-piece design is a major advantage over other tanks with replaceable atomizer heads. If the T3s atomizer head fails unexpectedly and the tank is filled with eLiquid, the atomizer head (base) can be easily replaced without the need to drain the eLiquid in the tank first
