Contributing Editor Josh Cosford shares his thoughts on what to do if a fitting detaches from an old hose:
With the exception of an improperly crimped hose, just say you went in and got a hose made, whatever the technician did, he made a mistake and did it to an improper crimp spec and it popped off immediately. You brought it back and you have enough room so that you can cut off 4 in. of that hose and then reuse it.
I think that’s the exception of when I would actually reuse a hose, when you knew it’s brand new, it’s barely been used and you can fit a fitting onto it and recrimp it. Otherwise, almost every other circumstance I would just get a new hose assembly. Hose is cheap, even like a half inch hose you’d be hard pressed to spend $20 more on it, depending on how long it is. Just get a new one made. That’s always the best practice.
