Good pressure resistance. The multi-layer steel wire winding reinforcement layer enables it to withstand higher pressure, making it suitable for high-pressure hydraulic systems. Four-layer steel wire winding high-pressure hose, The working pressure resistance can reach 70-112MPa.
Good corrosion resistance. The inner layer protects the steel wire from erosion by the conveying medium. The outer layer prevents the external environment from corroding the steel wire and the inner layer.
With advantages such as pressure resistance, fatigue resistance, and wear resistance, the wire-wound hydraulic hose has a high safety factor. Even in some extreme working conditions, such as sudden pressure shock or local physical damage, it has a certain ability to maintain integrity and avoid serious accidents such as hydraulic oil leakage. This is very critical in hydraulic system applications with extremely high safety requirements such as aerospace.
Due to the good performance of the inner rubber layer material, the wire-wound hydraulic hose is compatible with a variety of hydraulic media of different properties, including water-based hydraulic oil, petroleum-based hydraulic oil, emulsion, etc.

The wire-wound structure enables it to withstand very high pressure. Multiple layers of steel wire are spirally wound between the inner rubber layer and the outer rubber layer. When the internal pressure of the hydraulic system increases, the wire-wound layer can effectively resist the pressure and prevent the hose from breaking.
There is steel wire wrapped inside, but it still maintains good flexibility. This allows it to be easily bent and twisted during installation and can adapt to complex pipeline layouts. During the operation of the equipment, when the components in the hydraulic system undergo a certain degree of displacement or vibration, it can also deform appropriately and will not be easily damaged.


The wire-wound hydraulic hose can withstand frequent pressure changes and pulsations. It can resist such fatigue when the hydraulic system is frequently started and stopped or the working pressure fluctuates continuously. The wire-wound hydraulic hose can withstand pressure pulsation for a long time, extending the service life of the hose.
The inner rubber layer can prevent the hydraulic medium from corroding the steel wire, while the outer rubber layer can also resist the erosion of the internal structure of the hose by chemicals, moisture and oxygen in the external environment.
