Structural features: It is a multi-layer steel wire reinforcement layer with spiral winding. The spiral winding method of the steel wire allows the hose to be more evenly distributed in various parts of the hose when it is subjected to high pressure, enhancing its pressure resistance. Its working pressure is generally high and can withstand tens of MPa or even higher pressure.
Performance: It has excellent fatigue resistance. When the pressure of the hydraulic system changes frequently, it can maintain a good working condition and is not prone to damage due to fatigue. At the same time, it has good flexibility, is convenient for installation and layout, can be bent according to actual needs, and can adapt to more complex pipeline system layouts.
Sealing performance: It can effectively prevent hydraulic oil leakage and ensure the efficient operation of the hydraulic system. And it has good corrosion resistance. The internal steel wire reinforcement layer and the external rubber layer cooperate with each other to resist the corrosion of the hose by the external environment and hydraulic media.
hose is widely used in the hydraulic systems of various heavy machinery, construction machinery, agricultural machinery, and other equipment, and is a key component to ensure hydraulic power transmission.

It can withstand very high pressure, and the working pressure is usually above tens of MPa. This is because the spiral winding method of the multi-layer steel wire reinforcement layer enables the pressure to be evenly distributed in various parts of the hose, effectively enhancing the overall compressive performance of the hose.
Compared with some rigid pipes, this hose has better flexibility. It can be bent according to the actual installation requirements, with a relatively small bending radius, which can adapt to the complex hydraulic system pipeline layout and facilitate installation and connection in equipment with limited space.


The hose can maintain good performance under the frequent pressure changes and pulses of the hydraulic system. Due to the structural characteristics of the steel wire reinforcement layer and the use of high-quality rubber materials, the hose can withstand long-term pressure pulses and is not prone to fatigue damage such as rupture or leakage.
It has excellent sealing performance, the inner rubber layer is in good contact with the hydraulic medium, and the outer rubber layer and joints and other connection parts can effectively prevent hydraulic oil leakage. This is crucial to ensure the efficient operation of the hydraulic system and avoid environmental pollution.


The internal steel wire reinforcement layer and the external rubber layer cooperate to resist the corrosion of the hose by the external environment and hydraulic media. Whether in a humid environment, a place with chemical substances, or in contact with different hydraulic media, the performance of the hose can be kept stable.
