EN856 4SP Four Wire Spiral High Pressure Hydraulic Rubber Hose Manufacturers | PASSIONHOSE
EN 856 4SP is a rugged and reliable spiral-wire hydraulic hose built for demanding high-pressure circuits. Its four-spiral-steel-wire construction provides excellent strength, flexibility, and resistance to fatigue under pulsating pressure conditions. Unlike the 4SH standard which offers constant pressure across all sizes, 4SP features a pressure-decreasing design where larger diameters have lower working pressure ratings, making it a flexible and cost-effective option for a broad range of heavy-duty equipment. With a 4:1 safety factor and proven performance in construction, mining, and agricultural sectors, 4SP remains a trusted industry workhorse for medium- to high-pressure hydraulic applications.
