What is a hydraulic hose? In the answer, it should be said that it is used to transfer liquid between hydraulic components.

Hydraulic components can include: pumps, motors, valves, cylinders, tanks and many more. To create more strength when using systems at high pressure and temperature, the hydraulic hose consists of several layers. Hydraulic hoses are a vital part of a hydraulic system and due to their flexibility, they are able to bend and maneuver in tight spaces, which are known for such functions.


What are hydraulic hoses and what are they made of?


Normally, hydraulic hose has 3 main layers. In the first stage, the inner tube used to carry the fluid. It must be compatible with the type of fluid it carries and must also offer a certain flexibility. In the second step, the reinforcement layer that provides strength and determines the working pressure of the hose. The 3 most common types of reinforcement are braided, spiral and helical. Finally, the outer coating is often resistant to weather, oil, and abrasion, depending on the type of environment in which it is used. This adds an extra layer of protection. Our extensive line of hydraulic hoses and fittings are suitable for low, medium and high pressure applications.


5 ways to increase the life of the hydraulic hose:


A hydraulic hose should typically last up to 5 years. If yours fails in less than this time frame, external factors may be shortening their lifespan. Below we have provided 5 helpful tips on how to extend the life of your hose.

Make sure the hose is not stretched too tightly and there are no kinks, knots – this is usually due to improper installation and can cause structural weakness, but can be easily avoided if installed correctly.

Abrasion – External physical damage is the most common cause of hose failure. Ensuring that the hoses do not rub against each other or surrounding surfaces will help extend their life.

Protection – Adding a hose protector, cover, sleeve, or guard can help protect your hydraulic hose from wear, flame, and movement. Our hose protection equipment is designed to provide reliability and long-term protection not only for the hose, but also for the workers, as the hose sleeves retain the energy of potential explosions.


Maintenance – Managing multiple products can be difficult in maintenance, but it is a critical process that needs to be done.


Common hose problems:


Contamination – oil, dirty liquid passing through the hydraulic hose will cause damage to the inner tube and create holes. Additionally, not properly flushing the hose during assembly can cause contamination. It is recommended that the ends of the fittings be capped during transport. This minimizes the risk of recontamination and helps keep the hose clean.

Pipe Erosion – This usually causes an external leak and is caused by the high pressure of the liquid passing through the hose.

Incorrect Insertion Depth – If the hose assembly is not assembled correctly, the fittings can blow out the end of the hose.

General wear and tear – Hoses are put through tough applications on a daily basis. If not inspected regularly, they can cause leaks or bursts. Damage to the coating, the outer layer, is a good sign of internal deterioration.
