Specifications

Component type: High-Pressure Hydraulic Hose

Series: EN 856 4SH Hose

Material: Synthetic rubber compound reinforced with high-tensile steel wire spirals

Operating temperature: -40°C / +100°C

4SH is a premier heavy-duty, multi-spiral hydraulic hose engineered for extreme high-pressure fluid power systems subject to heavy pressure surges and severe mechanical loads. Unlike standard wire-braided hoses, the construction utilizes four alternating spirals of high-tensile steel wire. This robust multi-spiral architecture prevents the hose from expanding or twisting under high internal pressures, ensuring outstanding dimensional stability and superior impulse life. It is widely specified in heavy mobile machinery, high-capacity industrial presses, construction equipment, and high-pressure transmission lines requiring maximum reliability and safety margins.
