Yet a third type also works with non removable core but has a gripper extension thingy you can use to open and close the valve with.

There are also two different thread pitches, as it turns out. I've run into
the same problem. Vittorias (I think) have a finer thread pitch than most
others and the extenders have to match.

The tubes need to have removable valve cores.

Rick Johnson

As far as I am aware there's primarily two different kinds. Some go
directly over the Presta - which must be open - and are only good for
filling. These can be used with non-removable cores.
The ones Don describes are the kind I use, effectively they relocate the
Presta valve. Available in various lengths of course.

Every revolutionary idea seems to evoke three stages of reaction...
One, it's completely impossible.
Two, it's possible, but it's not worth doing.
Three, I said it was a good idea all along.

The tubes need to have removable valve cores.
Remove the core.
Thread extender to valve stem
Tread core into extender.
