Very helpful post, thank you for this, and for including the part numbers for the connector/sleeve!
Before coming across your post, I just called Festool to ask about cutting a 36mm hose and what parts I would need to add connectors at the cut ends. The rep I spoke with was emphatic, and repeated: "we do not recommend cutting the hose." He also told me that if I do cut the hose, I will not be able to attach new connectors to the cut ends.
I've seen several posts in the FOG from folks who have cut their hoses, specifically to make a shortened one for a Kapex (which is what I'm trying to do), and none who indicated they had trouble adding connectors to the cut ends. Is the Festool rep just telling me what he's been trained to say, or has something changed with Festool hoses such that some or all of the newer ones now cannot be used once cut? In case it matters, mine is a braided 36mm 3.5-meter hose (204924). I've searched far and wide for any video of someone cutting and/or re-attaching ends to a hose like this, but been unable to find one.
I've also tried removing the end from my hose without damaging it, to get a sense as to what re-attaching to a cut hose end might be like. After popping off the outer housing of the connector, which is simple enough with a flathead screwdriver, I've been unable to remove the black plastic ring that's attached to the hose end. I've read that this screws off, but that hasn't worked for me, so I wonder if this may be different for the braided hoses (or for the 204924 hose specifically).
I just posted to classifieds in search of a shortened hose, but would also be willing to cut the one I have. The Festool rep left me scared of that route, though, so I'm trying to do due diligence before cutting to make sure.
