DIN EN 856 4SH Steel Wire Spiral Hydraulic Hose
DIN EN 856 4SH hydraulic hose is a high-pressure rubber hose, mainly used for high-pressure, high-pulse hydraulic applications. The structure consists of three parts. The inner rubber layer of the 4SH hydraulic hose is made of oil-resistant synthetic rubber (such as nitrile rubber), the reinforcement layer is composed of four layers of alternating spirally wound high-strength steel wire, and the outer rubber layer is also made of oil-resistant synthetic rubber. It has excellent performance in delivering petroleum-based hydraulic fluids in the working temperature of -40 °C to +120 °C.

Application of 4SH high-pressure hydraulic hose
The 4SH high-pressure hydraulic hose is a four-layer steel wire reinforced rubber hose, conforming to the EN856-4SH standard. It features high pressure resistance, pulse fatigue resistance, and wide temperature adaptability, making it suitable for conveying petroleum-based hydraulic fluids, water-based liquids, and other media.
The core application areas of 4SH hoses include:
Mining and Petroleum Industry: Used in high-pressure, high-wear environments such as mine hydraulic supports, oil fracturing equipment, and drilling machinery, capable of withstanding frequent pressure fluctuations.
Construction Machinery and Heavy Equipment: Suitable for tunnel boring machines, excavators, cranes, etc., meeting the requirements of ultra-high-pressure systems for long service life and torsional resistance.
Ultra-high-pressure Cleaning and Special Operations: Used in water jet cleaning, injection molding machinery, and other applications, its high burst pressure (up to 4 times the working pressure) and wear resistance ensure safe operation.
Marine and Metallurgical Industries: Used in ship hydraulic systems and metallurgical forging equipment for transmitting hydraulic media, adapting to the corrosion resistance and high-temperature resistance requirements under harsh working conditions.

Strongflex Hydraulic Hose Manufacturer
We are a professional hydraulic hose manufacturer with our own factory. We strictly control every link from raw material procurement to finished product testing. The factory is located in Hengshui City, Hebei Province, a city with beautiful scenery and long history. It is equipped with 20 production lines, with a daily output of 50,000 meters, and its business covers more than 40 countries.
Raw materials:
Our rubber materials are imported from top suppliers in the international market (such as Sinopec), raw materials with high rubber content, and high-strength steel wire is purchased from domestic listed companies (such as Xingda Steel Tire Cord Co., Ltd).
High-quality materials provide our hydraulic hoses with stable performance, good strength and excellent oil resistance.
We will conduct a series of tests on the purchased materials, including rubber hardness test, steel wire tension test, etc. Unsuitable materials will not be put into production. Only qualified materials will be used to manufacture hoses.
Factory workshop:
Our factory introduces advanced technology and equipment to produce the best quality hydraulic hoses. High speed Spiral machine is used to produce steel wire spiral hydraulic hoses, which has the characteristics of high precision and high speed. The hoses produced can withstand 400,000 pulses.
Quality control:
We use two quality control systems, online and offline. Online, there is Enterprise Resource Planning that records the production process, operators, and operation dates, and offline, there is a manually filled hydraulic hose ID card. The quality tracking card is specially used to record the key parameters of the manufacturing process.
Finished product testing:
After production is completed, the product will be subjected to a series of tests such as pressure test, burst test, pulse test, etc. to ensure that the product you receive is qualified.
Packaging:
Our hydraulic hoses are normally packed with plastic films or woven bags. Special packaging can be customized according to customer requirements
