EN856-4SP FOUR-LAYER STEEL WIRE HYDRAULIC HOSE
the en856-4sp four-layer steel wire hydraulic hose is manufactured in accordance with the european en856 standard. the four-layer high-tensile steel wire cross-spiral structure provides the hose with excellent ultra-high pressure bearing capacity and pulse resistance. the oil-resistant inner tube is compatible with various mineral hydraulic oils, while the wear- and aging-resistant outer cover protects against outdoor oil contamination and uv degradation. with outstanding bending performance, it can reliably deliver hydraulic media under long-term heavy-duty alternating pressure conditions, making it ideal for complex pipeline installations in heavy-duty equipment.
