Hydraulic Hose DIN EN 856 4SH very high pressure, pulsating applications used for petroleum-based hydraulic fluids. Wire wrapped in alternating directions, and oil and weather-resistant synthetic rubber cover.4sh high-pressure hose. The Hydraulic Hose DIN EN 856 4SH is a type of hydraulic hose that conforms to the DIN EN 856 4SH standard. This standard specifies the requirements for high-pressure hydraulic hoses used in demanding applications. The hose is designed to withstand extreme pressures and provide efficient transmission of hydraulic power. The designation "DIN EN 856 4SH" refers to the German Institute for Standardization (DIN) standard and the European Norm (EN) standard that govern hydraulic hoses. DIN EN 856 4SH outlines the construction, performance, and compatibility of the hose with hydraulic fluids, ensuring its reliability and performance in high-pressure hydraulic systems.

Hydraulic Hose DIN EN 856 4SH High-pressure hose with four layers of high tensile steel wire. This product can be used for hydraulic systems of ultrahigh pulsating pressure with high-temperature working fluids for oil-based. The DIN EN 856 4SH hydraulic hose is commonly used in heavy-duty hydraulic systems found in industries such as construction, mining, and agriculture. It is capable of handling extremely high hydraulic pressures and effectively transmitting hydraulic power between various components, including pumps, valves, cylinders, and motors. When selecting this hydraulic hose, it is important to consider factors such as the required hose size (diameter), pressure rating, temperature range, and compatibility with hydraulic fluids used in the system. Adhering to manufacturer guidelines and industry standards for hose installation, routing, and maintenance is crucial to ensure optimal performance and longevity.

Frequently Asked Questions
What is the difference between 4SH and 4SP hydraulic hose?
The 4SH uses four spiral layers of heavier-gauge high-tensile steel wire compared to the 4SP, giving it a higher working pressure rating and better impulse performance. Both meet DIN EN 856, but 4SH is designed for the most demanding high-pressure applications.
What is the maximum working pressure?
Working pressure can reach up to 6,530 PSI (450 bar) for smaller diameters, with a minimum burst safety factor of 4:1 as specified in DIN EN 856 4SH.
What applications is the 4SH hose suited for?
Designed for extreme duty applications including large excavators, offshore drilling equipment, hydraulic presses, injection molding machines, and any system where pressure spikes and continuous high-pressure operation are expected.
What is the temperature operating range?
Standard construction operates between −40°C and +120°C (−40°F to +248°F) for petroleum-based hydraulic fluids, making it suitable for both cold-climate machinery and hot industrial environments.
Is the 4SH hose more difficult to route than lower-specification hoses?
Yes. The four-layer heavy wire spiral construction makes 4SH hose stiffer, with a larger minimum bend radius. Careful routing and clamping design is required. Our technical team can advise on bend radius and hose length calculations.
What fittings are compatible?
Swage-type fittings designed for 4SH hose are required. Standard JIC, BSP, and metric DIN fittings in the appropriate 4SH swage ferrule are available from Sunhose.
What is the minimum order quantity?
Standard MOQ is 1,000 meters. Custom assemblies and test-certified hose assemblies for critical applications are available — please contact our sales team.
