EN853 2SN 40Mpa hydraulic hose | hose assembly

As a high-performance industrial machinery accessory, EN853 2SN 40Mpa hydraulic hose plays a vital role in modern engineering machinery and hydraulic systems. Litong Hydraulic Hose Division wrote the structural characteristics, significant advantages and wide use of EN853 2SN 40Mpa hydraulic hose in various application scenarios on March 18, 2025.

 

 

The structural design of EN853 2SN 40Mpa hydraulic hose is precise. It mainly consists of three parts: inner rubber layer, reinforcement layer and outer rubber layer. Each layer has a specific function, which together ensures the high performance and long life of the hose.

Inner rubber layer: As the innermost layer of the hose, it is in direct contact with the transmitted medium, so the inner rubber layer needs to have excellent oil resistance. The inner rubber layer of EN853 2SN hose is usually made of black oil-resistant synthetic rubber, which can not only effectively resist the erosion of media such as mineral oil and polyethylene glycol-based hydraulic oil, but also maintain stable performance in a wide temperature range of -40℃ to +100℃.

 

Reinforcement layer: The reinforcement layer is a key part of the hose structure, which determines the pressure bearing capacity and tensile strength of the hose. EN853 2SN hose is woven with two layers of high-strength and high-tensile steel wire to form a tight reinforcement layer (2w/b). This design not only improves the pressure bearing capacity of the hose, enabling it to withstand working pressures up to 40Mpa, but also enhances the hose's pulse resistance and wear resistance, ensuring reliable operation under harsh working conditions.

 

Outer rubber layer: The outer rubber layer is the protective layer of the hose, and its main function is to prevent the hose from being damaged by the external environment. The outer rubber layer of the EN853 2SN hose is also made of oil-resistant, corrosion-resistant, and wear-resistant synthetic rubber, with a cloth-textured appearance, which not only improves the beauty of the hose, but also increases its friction with the surrounding environment to prevent the hose from slipping during movement. In addition, the weather resistance of the outer rubber layer also ensures the long-term stability of the hose in outdoor environments.

 

 

EN853 2SN 40Mpa hydraulic hose is widely used in the industrial field due to its many significant advantages:

 

1. High pressure bearing capacity: Thanks to its unique two-layer steel wire braided reinforcement layer design, EN853 2SN hose can withstand working pressure up to 40Mpa, meeting the needs of various high-pressure hydraulic systems.

 

2. Excellent oil resistance: The inner rubber layer is made of oil-resistant synthetic rubber, which ensures the stability and reliability of the hose when transmitting various oil media.

 

3. Good heat resistance and weather resistance: The outer rubber layer of the hose has excellent heat resistance and weather resistance, and can maintain stable performance in a wide temperature range of -40℃ to +100℃, suitable for various harsh environments.

 

4. Strong pulse resistance: The tightly woven structure of the reinforcement layer improves the pulse resistance of the hose, enabling it to maintain stable operation under high-frequency pulse pressure.

 

5. Good wear resistance: The outer rubber layer of the hose is made of wear-resistant synthetic rubber, which effectively extends the service life of the hose.

6. Easy installation: The crimping joint of EN853 2SN hose does not need to peel the outer rubber, which simplifies the installation process and improves work efficiency.

 

 

EN853 2SN 40Mpa hydraulic hose has been widely used in the industrial field due to its excellent performance and wide applicability:

 

1. Engineering machinery: In engineering machinery such as excavators, loaders, and rollers, the hydraulic system is one of its core components. EN853 2SN hose has become an ideal choice for hydraulic pipeline systems in these equipment due to its high pressure bearing capacity and anti-pulse performance.

 

2. Metallurgical equipment: In the metallurgical industry, various heavy machinery and equipment need to withstand high temperature, high pressure and harsh working environment. EN853 2SN hose plays an important role in these equipment due to its good heat resistance, weather resistance and wear resistance.

 

3. Oil drilling: During the oil drilling process, the hydraulic system needs to withstand extremely high pressure and temperature. EN853 2SN hose has become an indispensable component in oil drilling equipment due to its excellent pressure bearing capacity and oil resistance.

4. Shipbuilding: In the shipbuilding industry, hydraulic systems are widely used in equipment such as steering gears, anchor winches, and winches. EN853 2SN hoses are widely used in these equipment due to their compact structure and good weather resistance.

5. Agricultural machinery: In agricultural machinery, hydraulic systems are used to drive various agricultural implements and equipment. EN853 2SN hoses have become the preferred material for hydraulic pipeline systems in agricultural machinery due to their high pressure bearing capacity and wear resistance.

 

In addition, EN853 2SN hoses are also widely used in aviation, railways, refrigeration and other fields, and their excellent performance and wide applicability have been unanimously recognized by the industry and outside.

 

In summary, EN853 2SN 40Mpa hydraulic hoses play a vital role in the industrial field with their unique structural design, significant advantages and wide application scenarios. With the advancement of science and technology and the development of industry, EN853 2SN hoses will continue to innovate and improve, providing more reliable and efficient solutions for hydraulic systems in all walks of life.
