a cartridge part configured for use with a reusable part, the cartridge part comprising
a cartridge housing,
a reservoir formed within the cartridge housing for containing liquid for vaporization,
a vaporizer disposed within an air path forming a vaporization chamber within the cartridge housing, and
a liquid transport element arranged within a channel from the reservoir to the vaporization chamber to transport the liquid from the reservoir to the vaporizer for vaporization, the liquid transport element being formed with the vaporizer in the vaporization chamber to convey the vapor in use when air is drawn by a user through the air path, and
a sealing element, the sealing element comprising a plurality of fingers projecting outwardly opposite one another from one end of a stalk, wherein when located in a sealing position the plurality of fingers of the sealing element are configured to extend into the channel to reduce a cross-sectional area of the liquid transport element in the channel and the stalk of the sealing element extends proud of the cartridge part so that the sealing element can be removed by the user before the cartridge part is used.
