EN 856 4SH Hydraulic Hose
High Pressure Hose EN 856 4SH
EN 856 4SH hose is a hydraulic hose with a high-pressure rating, which makes it suitable for heavy-duty industrial applications where fluids need to be reliably transferred under extreme pressure conditions.
It is commonly used in construction machinery, mining equipment, and oil and gas drilling platforms to handle hydraulic fluids such as glycol, mineral oil, fuel, water, and air.
Its four-ply high-strength steel wire-spiral construction and resistance to abrasion, weather, and oil make it a reliable choice for fluid transfer in harsh environments.

What is EN 856 4SH Steel Wire Spiral Hydraulic Hose
This EN 856 4SH Steel Wire Spiral Hydraulic Hose has a higher working pressure performance, so it is very suitable for extremely high pressure working conditions. It has excellent performance in conveying petroleum-based hydraulic oils in the working temperature range of -40 ยฐC to +100 ยฐC. It consists of three parts: barrel, reinforcement and protective layer. The hose is made of black oil-resistant synthetic rubber, which makes the hose work well when conveying oil. The reinforcement is made of four layers of high-strength high-strength spiral steel wire, which is specially designed for rubber hoses. Therefore, the hose is resistant to high pressure and has outstanding performance under high-pressure working conditions. The outer shell is made of black oil-resistant, corrosion-resistant, abrasion-resistant, weather-resistant and ozone-resistant synthetic rubber, and the appearance is cloth pressed rubber.
Where EN 856 4SH Steel Wire Spiral Hydraulic Hose can be used
Extremely high pressure and high pulse hydraulic applications. This hose is the most flexible EN 856 4SH hose in the industry with superior impulse performance (tested to 1,000,000 impulse cycles at a bend radius lower than the EN 856 standard). Compatible with biodegradable hydraulic fluids such as synthetic esters, polyglycols and vegetable oils as well as petroleum based hydraulic fluids. Hydraulic hose EN 856 4SH can deliver hydraulic oil, liquid as well as gas. It can transfer petrol based liquid such as mineral oil, hydraulic oil, fuel oil and lubricant.

Differences between EN 856 4SP and EN 856 4SH
Hydraulic hoses EN 856 4SP and EN 856 4SH have the same structure. Both have an inner tube, a reinforcement layer and an outer layer. In addition, they are both suitable for extremely high pressure applications. However, the reinforcement layer is different. EN 856 4SP is reinforced with 4 layers of steel wire braid. But EN 856 4SH is a steel wire spiral layer. In fact, the steel wire braid reinforcement layer can withstand higher pressures. But EN 856 4SH is also suitable for your tough hydraulic work.
4 SP high-pressure hoses are reinforced with steel wire and are designed for medium pressure levels in hydraulic systems; 4 SH high-pressure hoses are reinforced with spring coils made of high-strength steel wire and are designed for high-pressure hydraulic systems.

Technical characteristics of 4SH high-pressure hoses
The operating parameters of hoses in the 4SH category meet the requirements of EN ISO 1402, including indicators such as maximum pressure and abrasion resistance. In order to select a hose suitable for the working conditions, the following characteristics of the hose need to be taken into account:
Nominal channel diameter. The indicator ranges from 19 to 51 mm, depending on the model. This parameter is reflected in the marking: Hose RVD 4SH 25, 32, 38, etc.
Working pressure. RVD 4SH - Extremely high-pressure hose. Depending on the inner diameter, this number ranges from 250 to 420 atmospheres.
Burst pressure. For hoses with four spiral reinforcement layers, this number ranges from 1100 to 1680 atmospheres.
Bending radius. This type of hose hose is not highly flexible. The indicator range is from 280 to 700 mm.
Operating temperature. Most 4SH hoses are suitable for operation in a temperature range of -40 to +100 degrees. A short-term increase to +120 degrees is possible.
Outer and inner diameter. Select according to the type of equipment and the outlet diameter.
