DIN-EN 856 4SP 4-Ply Steel Wire Spiral Hose
1. Product Overview
A high-pressure hydraulic hose complying with DIN-EN 856 4SP standard, reinforced with 4-ply high-strength steel wire spiral winding. It features reliable oil resistance, wear resistance and weather adaptability, providing stable and durable fluid transmission for high-pressure hydraulic systems.
2. Construction Details
- Inner Tube: Oil-resistant synthetic rubber (ensures excellent compatibility with hydraulic fluids and maintains structural integrity under high-pressure conditions)
- Reinforcement Layer: Four plies of high-strength steel wire spiral winding (delivers superior pressure-bearing capacity to meet high-pressure working requirements)
- Outer Tube: Wear-resistant & weather-resistant synthetic rubber (prolongs service life in harsh working environments and enhances environmental adaptability)
3. Technical Parameters
- Standard Compliance: DIN-EN 856 4SP
- Operating Pressure: High pressure
- Temperature Range: -40℃ to +121℃
- Compatible Fluids: Hydraulic oil, mineral oil (and other oil-based hydraulic fluids)
- Reinforcement Specification: 4-ply high-strength steel wire spiral winding
- Minimum Bending Radius: [Optional: Fill in specific value by size if available]
- Length: [Optional: Customizable or standard lengths (e.g., 10m/20m per roll)]
4. Application Scope
Designed specifically for high-pressure hydraulic systems. Suitable for industrial machinery, heavy-duty equipment, hydraulic power units and other scenarios requiring reliable fluid transmission under high-pressure conditions.
5. Usage Notes
- Strictly operate within the specified temperature and high-pressure limits to avoid performance failure or safety hazards.
- Avoid dragging, twisting, or contact with sharp objects during installation to prevent damage to the outer tube and spiral reinforcement layers.
- Use joints matching DIN-EN standards and follow professional crimping procedures to ensure tight sealing under high pressure.
- Store in a dry, well-ventilated area, away from direct sunlight, high temperatures and corrosive substances.
