APPLICATIONS:

The EN 856 4SP hose is a high-pressure hose designed to convey hydraulic fluids in industrial, agricultural, and other applications that require a robust and reliable hose capable of withstanding high pressures and harsh conditions. The "4SP" designation indicates that the hose has four layers of spirally wound steel wire for strength and pressure resistance, and it is designed to meet the performance specifications outlined in the European standard EN 856.

Key features and specifications of the EN 856 4SP wire spiral hydraulic hose include:

- **Pressure Rating**: The hose is rated for working pressures up to 450 bar (6,530 psi) depending on the size and manufacturer.

- **Temperature Range**: It can operate in a wide temperature range, typically from -40°C (-40°F) up to +100°C (+212°F), although this can vary based on the specific fluid being conveyed.

- **Construction**: The hose consists of a synthetic rubber inner tube, which is compatible with hydraulic fluids, a reinforcement layer of high-tensile steel wire spirals for pressure resistance, and an outer cover of synthetic rubber for protection against environmental factors.

- **Applications**: It is suitable for use in hydraulic systems in various industries, including construction, mining, agriculture, and marine applications where high pressure and durability are required.

- **Abrasion Resistance**: The hose is designed to have good resistance to abrasion, which is important for applications where the hose may come into contact with rough surfaces or be subjected to harsh environmental conditions.

- **Chemical Resistance**: The materials used in the hose are selected for their resistance to the most common types of hydraulic fluids, including mineral oils and certain types of synthetic fluids.
