The EN856 4SH hydraulic hose is a heavy-duty, high-pressure solution engineered for use in the most demanding hydraulic applications. Built with four layers of high-tensile steel wire spiral reinforcement, this hose is specifically designed to handle extreme pressure levels and high-impulse conditions, making it ideal for critical systems operating in tough industrial environments.
What sets the EN856 4SH apart is its exceptional pressure resistance, with working pressures typically ranging from 25 to 45MPa depending on hose size. The four-layer spiral construction ensures superior strength and structural integrity, allowing it to perform reliably under constant high-pressure conditions. This makes it particularly well-suited for applications such as construction equipment, mining machinery, offshore platforms, and other high-load hydraulic systems.
In addition to its pressure handling capabilities, the EN856 4SH hose offers excellent impulse fatigue resistance, enabling it to withstand millions of pressure cycles without failure. This durability reduces the risk of unexpected downtime and lowers maintenance costs over the hose’s operational life.
The inner tube is made of high-quality, oil-resistant synthetic rubber, compatible with a wide range of hydraulic fluids including mineral oils, synthetic oils, and water-based fluids. The outer cover is abrasion-, ozone-, and weather-resistant, providing additional protection in harsh working environments and extending the hose’s service life even under aggressive mechanical or environmental stress.
Despite its rugged construction, the EN856 4SH hose maintains a practical level of flexibility for installation and routing, particularly in large equipment where both high pressure and movement are present.
With its four-wire spiral reinforcement, high-pressure rating, and long-lasting performance, the EN856 4SH hydraulic hose is a trusted choice for professionals requiring strength, reliability, and durability in their hydraulic systems.
