If you’re going to mis-measure cutting a hose, what’s the better problem to have: too long or too short? It is probably better to have a hose that is too long as opposed to too short. A hose that is too short tends to put pressure on the connection between the hose and the fittings. That is usually the number one spot of failure in a hydraulic hose. There are chances of a hose somewhere in the middle are getting pinched or damaged physically, but wear over time happens between two places that can’t move. The hose can move but the fitting cannot, and that causes tension or compression and wear right at the connection between the hose and the fitting.
When you try to make and connect hoses that are too tight, you create that tension and you will likely end up with premature hose failure. If a hose is too long, you risk it laying where it shouldn’t, rubbing on things that it shouldn’t. That can cause a quick failure, too, if there’s a lot of vibration, but it at least allows for enough slack in the hose. You can always use hose clamps and clamp down a hose that’s too long, but in general, it’s better to go for a hose that is longer than shorter.
