- 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.
