Why would you replace a hydraulic hose?

It is too long
It has a leak, blister, swelling, or bad end fitting
It is too rigid
It is discolored

The correct answer is: It has a leak, blister, swelling, or bad end fitting

Replacing a hydraulic hose is crucial when it exhibits signs of a leak, blistering, swelling, or has a bad end fitting. These conditions indicate that the integrity of the hose is compromised, which can lead to fluid loss, decreased performance of the hydraulic system, and potentially hazardous situations. Hydraulic systems operate under high pressure, and any failure in the hose can result in serious accidents, equipment damage, or even personal injury. While issues such as being too long, too rigid, or discolored may affect functionality or aesthetics, they do not pose an immediate risk to safety or system performance like a leaking or damaged hose does. Thus, the presence of physical damage or deterioration due to wear is the most critical indicator that replacement is necessary.
