For deep rims: the extender screws in between the valve body and the core, with an O-ring against leaks.

For deep-profile rims, when the valve doesn't stick out enough to connect a pump. In the shop, it is called “Tufo Valve Extension”.
The extender screws in between the valve body and its core : unscrew the core, screw the extender onto the body, then screw the core back on at the top of the extender. So it's the core that sticks out of the rim, and you inflate exactly as usual — including to inject sealant.
It is fitted with an O-ring at the junction: this prevents the slow leak that cheap metal-on-metal screw-on extenders produce. Aluminium, in 21, 28 or 31 mm, sold individually.
