If you frequently need a hose repair on the same hose or section of the hose, you might find that there is a logical explanation for this.

Several common circumstances can lead to damage to hydraulic hoses, which you can investigate. The four most common causes of damage to hydraulic hoses will be outlined here, to help you keep your hoses in top condition and prevent unnecessary damage.

1) Abrasion Will Cause Damage

The pressure inside hydraulic hoses is not constant, so as the pressure fluctuates, it causes compression or expansion of the hose. This, in turn, means that the hose is not static. One of the outcomes of this movement in the hose is that it can rub against objects, causing wear and tear to the outer cover of the hose.

Eventually, the steel wires that reinforce the hose may become exposed, and leaks can occur. This is one of the most common factors that precipitate hose repair.

2) High Temperatures Lead To Hose Repairs

Hydraulic hoses subjected to high temperatures will soon deteriorate and become inflexible. The inner plastic tube will harden and crack until the hose eventually starts to leak, necessitating a hose repair.

3) Improper Installation And Routing

The problems of abrasion and exposure to high temperatures can be avoided by paying better attention to the installation and routing of hydraulic hoses, thus reducing the need for hose repair. The hoses should not be installed in places where movement is likely to cause abrasion, and they should be re-routed away from high-temperature zones to ensure the longevity of the hose.

In addition, to avoid hose repairs, hoses should be installed without excessive bending, as coils or kinks in the hose make them more susceptible to damage.

4) The Incorrect Hose For The Job

Different types of fluids are used in hydraulic systems. To avoid hose repair, you must match the hose type to the fluid type. If the incorrect fluids are passed through a hydraulic hose, it can cause damage and the ultimate deterioration of the inner tube leading to leaks and contamination. It is vital to ensure that you select the correct hose for your application.
