This is the swivel mechanism for the high pressure air at the center of my Campbell Hausfeld automatic retracting air hose reel. That hose is crimped directly on the swivel mechanism instead of adding negligible cost with a threaded fitting.
The upshot is that the hose is not replaceable by itself if damaged. And of course parts are not readily available. Throw out the whole thing instead and buy something new. Assholes.
It's really more about automated assembly which ultimately is about saving labor cost. A worm clamp is impossible to automate. The crimps are more reliable and easier to automate.
Here is the manual assembly process, and per usual, disassembly is the reverse

More like carefully cutting through the ferrule without damaging the barb.
I wouldn’t have expected a worm clamp in here, but a standard air hose is crimped onto a threaded end (same as on the pigtail for this reel). Female threads on an angled exit from the swivel would make hose replacement easy, without adding significant labor (there are already two threaded connections on this unit).
Yesterday I just cut the hose short to get up and running again, but I’ll use your suggestion later when I get fed up with the short hose and open up the reel again. Thanks!
