Can a cigarette lighter cause an explosion?
Something as small as the flame from a cigarette lighter can cause a dangerous explosion. For this reason, avoid open flames and sparks near a suspected leak. That includes welding equipment, lit cigarettes, and cutting torches. Use a flashlight around hydraulic systems when you need to see more clearly, never a lighter.
Why use an angled fitting?
Many pieces of equipment use angled fittings to route their hoses and allow hydraulic oil to flow more freely. If an angled adapter or coupling is required, install the angled fitting first to ensure correct positioning. Once the angled adapter is in place, the end of the hose assembly can be threaded onto the adapter or port.
What to do if hydraulic hose is leaking?

Because of this, there may also be different types of hydraulic hoses with various minimal pressure ratings on a single piece of equipment.
Is a hydraulic hose too short?
Hydraulic systems are constantly under pressure, and a hose that is too short will be more prone to a dangerous (and costly) failure. Once the hose is the appropriate length, be sure that it is properly routed. This will enable the rest of the hydraulic system to function normally.
