The EN 856 4SP rubber hose is a four-layer, steel-wire spiral-reinforced high-pressure hydraulic hose manufactured in strict compliance with the DIN EN 856 standard.
The EN 856 4SP rubber hose is a four‑layer, steel‑wire‑spiraled, high‑pressure hydraulic hose manufactured in strict compliance with the DIN EN 856 standard. It is specifically designed for high‑pressure applications involving petroleum‑based hydraulic fluids. With outstanding mechanical performance and excellent environmental resistance, it serves as a critical component in harsh operating environments such as heavy machinery, forestry, and mining, delivering reliable performance and an extended service life.
High-pressure resistance: A four-layer steel wire spiral construction combined with premium rubber material ensures that, at the same operating temperature, the working pressure exceeds that of comparable EN 856 4SH hoses, delivering a stable and reliable high-pressure rating.
Environmental adaptability: It exhibits flame resistance, antistatic properties, wear resistance, and pulse‑fatigue resistance, enabling long‑term operation under harsh outdoor conditions, making it particularly well suited for heavy‑duty applications such as forestry and mining equipment.
Durability: The aging resistance of the outer jacket, combined with the oil‑resistant and corrosion‑resistant properties of the inner tube, significantly extends the hose’s overall service life and reduces replacement and maintenance costs.
Primarily designed for high-pressure hydraulic systems in heavy machinery, forestry equipment, mining equipment, and other applications, as well as for hydraulic line conveyance under extreme outdoor operating conditions, it is an ideal complementary component for high-pressure hydraulic transmission and control in industrial settings.
EN 856 4SP
Structure: The hose consists of an oil-resistant synthetic rubber inner liner, four layers of coarse steel wire spirals wound in alternating directions, and an outer layer of oil- and weather-resistant synthetic rubber.
Application: Suitable for hoses used with petroleum-based hydraulic fluids, operating within a temperature range of -40°C to +100°C.
