The ferrule has a ******* thread which you wind on the hose, there are
different types depending on whether you skive off the outer rubber
first or not or how many steal braid layers the hose has, you then wind
the coupling in and the taper grips the hose to the ferrule.

So no need for an outer crimp / ferrule or is there still one?

No the taper thread screwing into the ferrule which is already screwed
onto the hose with a reverse thread replaces the need for crimping.

Ah, gotcha.

The ferrules for one type of hose are then used with whatever end you
want, of the type in the link.

Cool.

I am only saying you can use it to adapt fittings for testing, certainly
not for use in hydraulic components for brake systems of vehicles.

Understood ... and exactly how I would be using it (testing).
