Many times, our customers will order a certain length of hose, knowing they'll need to trim the size before putting it into use. But the question is, "If you're going to mis-measure cutting a hose, what's the better problem to have: too long or too short?"
Sometimes, even a quarter of an inch can make a huge difference in whether or not your hose properly fits the application for which it's intended.
In reality, you want it to be just right. Hose length really is critical to avoid premature hose failure due to unnecessary tension.
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. Granted, there are chances of a hose somewhere in the middle is getting pinched or damaged physically, but wear over time happens between two places that can't move.
That's what you get when the hose can move but the fitting cannot causing tension or compression and wear right at the connection between the hose and the fitting. When you try to connect hoses that are too tight, you create that tension and you will likely end up with premature hose failure.
On the other hand, if a hose is too long, you risk it laying where it shouldn't and potentially rubbing on things that it shouldn't. That can cause a quick failure, too. If there's a lot of vibration, 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, so in general, it's better to go for a hose that is longer than shorter.
Remember the old adage, "Measure twice. Cut once." That definitely should apply to your hose length. If your hose is too long or too short when you have two 45 or 90 degree Split Flange hose ends at different phase angles in a 4 or 6 spiral wire hose you're asking for problems down the line.
One way to avoid that problem is to have us come out and assist you in confirming correct dimensions or you can always bring the existing hose assembly that needs replacement to our facility and we will fabricate a new hose assembly while you wait. We'll be happy to help make sure you're getting the right sized hose for your particular need.
