It doesn’t collapse when routed over the edge, if that’s what you’re asking.
I don’t think 75’ would fit, especially of 3/4” hose. When I replaced mine I used about 40’ of 1/2” hose, which is what came off my reel, and that filled up my reel. The nipple on my reel is 1/2”, and I’ve not had much success putting larger hoses on there (I tried with 5/8” hose before going down to 1/2” hose.).
