Manguera hidráulica EN 856 4SH
High Pressure Hose EN 856 4SH
The 4SH Spiral Steel Wire Hydraulic Hose features a four-spiral steel wire inner core for enhanced strength and durability, suitable for high-pressure applications.
This design withstands extreme pressures and temperatures ranging from -40°F to 212°F, ensuring reliable hydraulic performance under harsh conditions.
Its synthetic rubber cover is highly tolerant to adverse weather conditions, oil, and abrasion, MSHA approved. And EN 856 4SH/DIN 20023 4SH 4-ply spiral hydraulic hose for very high-pressure applications and pulse cycles, and it mainly used in the oil-pressure equipment sector where medium-high pressures ranging from 250 to 420 bars for industries such as Oil & Gas, Mining, Steel, Forestry, and other industries.
It has nominal diameters from 3/4" to 2". It tolerates pressures from 3500 PSI to 6000 PSI. It has excellent performance in delivering petroleum-based hydraulic fluids in the working temperature of -40 °C to +100 °C. Its main difference with the 4SP hose is that the 4SH hose tolerates higher pressures.
For installing the couplings, the “skiving” operation must be performed. For better sealing, the use of multispiral fittings is recommended.

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 °C to +100 °C. 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.

Differences between EN 856 4SP and EN 856 4SH
Mangueras hidráulicas EN 856 4SP y 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.
