How to Select Hydraulic Hose: 4SP vs 4SH Hydraulic Hose
As widely used hydraulic hose types in high-pressure hydraulic systems, both EN 856 4SP and 4SH feature a four-layer high-strength spiral steel wire reinforcement structure. They offer excellent pressure resistance and pulse resistance, making them the mainstream choice for high-pressure hydraulic circuits. They are commonly used in construction machinery, mining equipment, and industrial hydraulics.
However, while EN 856 4SP and 4SH are structurally very similar, they differ significantly in certain characteristics, making them incompatible for interchangeable use. This often leaves many buyers and engineers unsure of which option to choose for their specific applications. Therefore, this article provides a detailed explanation of the
