Why hydraulic hoses burst, leak, or rub through

Hydraulic hoses usually fail from three main causes: pressure spikes that exceed their rating, abrasion from rubbing against machine parts or other hoses, and age-related deterioration of the inner tube. Heat and improper routing also weaken the cover, while contaminated or incompatible hydraulic fluid can soften the rubber from inside. Even proper assemblies can eventually burst if the braided reinforcement fatigues from repeated flexing.
