Reusables have their place. Personally, I don't like them. They are bulky and I have seen hoses pull out of them. You can only get them in 100R2 hose (2-wire thick cover). You can get them in limited sizes for other hoses, but it's really not worth the bother. The 100R2 hose is 1970's technology at best. I would rather get a good crimped 100R16 hose. All the same pressure specs but smaller O.D. and half the bend radius. There's even the new EN spec hoses that have a higher pressure rating and all the same other specs as 100R16 hose. For a lot of you guys, reusables are a good way to go. And this is coming from a guy that owns a hydraulic hose shop. But if you have any problems, go get a 100R16 hose or better yet an EN spec hose.
You can find used crimpers on E-bay reasonable. There's a dealer called Surplus Hose Man that is very good to deal with.
