Which of the following can contribute to the abrasion of hydraulic hoses?

The correct answer highlights that contact with sharp edges or rough surfaces significantly contributes to the abrasion of hydraulic hoses. When hydraulic hoses come into direct contact with any protruding or uneven surfaces, the friction and pressure can wear down the material of the hose over time. This leads to compromised integrity, increased risk of leaks, and potential failure of the hydraulic system.

Maintaining a proper routing of hoses away from sharp or abrasive edges is crucial in hydraulic system design and maintenance to ensure longevity and optimal performance. By understanding this, one can proactively prevent damage and ensure the reliability of hydraulic systems in various applications.

The other options do not directly relate to the mechanical wear and tear process associated with abrasion. Excessive moisture can cause degradation of the hose material but is not a direct cause of abrasion. Using hoses with excessive wall thickness may provide additional strength but doesn’t address the issue of abrasion. Insufficient torque on fittings more so relates to connections than to the physical wear process of the hoses themselves.
