The 4SH spiral‑wire hydraulic hose features a four‑layer spiral‑wire reinforcement core, delivering superior strength and durability thanks to its high‑strength construction. Designed for high‑pressure applications, it reliably withstands extreme pressure conditions.
The 4SH spiral‑wire hydraulic hose features a four‑layer spiral‑wire reinforcement core, delivering superior strength and durability thanks to its high‑strength construction. Designed for high‑pressure applications, it reliably withstands extreme pressure conditions.
This hose boasts exceptional temperature resistance, with an operating temperature range spanning from –40°C to +100°C, ensuring stable and reliable hydraulic system performance even in harsh environments. Its synthetic rubber outer jacket offers superior weather resistance, oil resistance, and abrasion resistance, effectively guarding against adverse weather conditions, oil exposure, and everyday wear, thereby extending its service life.
The product strictly complies with the EN 856 4SH standard and exceeds the relevant requirements of both EN 856 4SH and DIN 200023 4SH, making it suitable for medium- and high-pressure hydraulic systems and pulse‑cycling applications. It is widely used in heavy industries such as oil and gas, mining, steel, and forestry.
In terms of specifications, the nominal diameters range from 3/4 inch to 2 inches, delivering outstanding performance when conveying petroleum-based hydraulic fluids within a temperature range of –40°C to +100°C. Compared with 4SP hoses, 4SH hoses offer superior pressure‑rating capabilities, making them well suited for applications requiring higher operating pressures.
During installation, to achieve superior sealing performance, it is recommended to use multi‑helix pipe fittings, thereby further ensuring the hydraulic system’s sealing reliability and operational stability.
EN 856 4SH
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.
