EN856 4SH Hydraulic Hose

Q: What makes EN 856 4SH different from EN 856 4SP?

Both are spiral wire hoses, but 4SH is designed for higher pressure resistance and heavier duty applications compared to 4SP.

The EN 856 4SH hydraulic hose is a four-spiral wire reinforced high-pressure hose, specifically designed for demanding hydraulic applications. It offers superior strength, excellent flexibility, and reliable performance under continuous high-pressure conditions. With an oil-resistant synthetic rubber tube, four layers of high-tensile spiral steel reinforcement, and a weather- and abrasion-resistant synthetic rubber cover, the 4SH hose ensures long service life even in harsh environments. It is widely used in construction machinery, mining equipment, agricultural machinery, and other heavy-duty hydraulic systems where ultra-high pressure and durability are required.
