What is the determining factor of strength in a flexible rubber hydraulic hose?

The determining factor of strength in a flexible rubber hydraulic hose is significantly influenced by the external cover. The external cover is designed to protect the hose from environmental factors such as abrasion, ultraviolet light, ozone, and chemicals, which can all weaken the integrity of the hose over time. A robust external cover enhances the overall durability and longevity of the hydraulic hose while maintaining its ability to handle pressure and fluid flow effectively.

Although the internal pressure rating, the type of rubber, and the length of the hose play important roles in the performance of a hydraulic hose, it is the external cover that is crucial for protecting the structural integrity and ensuring that the hose can withstand various challenges and stresses during operation. Selecting a hose with a strong and suitable external cover is essential in hydraulic applications to prevent premature failure and maximize safety.
