70 MPa Hydraulic Hose With Extremely Tight Bend Radii And Superior Flexibility
Product Advantages
Our lightweight thermoplastic hydraulic hose is reinforced with aramid fiber for high strength without the weight of traditional rubber hoses. Perfect for marine cranes, deck machinery, and hydraulic power units (HPUs), it offers lower permeation rates and better thermal stability than standard rubber hoses.
Key Benefits
• High temperature resistance
Continuous use at 125°C (peak 150°C).
• Lightweight flexible
Reduces system weight, improving fuel efficiency.
• Chemical seawater resistant
Ideal for offshore drilling and ship hydraulics.
• Certified performance
Complies with EN 857 2SC, DIN 20023, and marine safety standards.

More Than Just a Hose
• Structural Design
Multi-layer thermoplastic (Parker TPE) construction with aramid fiber reinforcement. Lightweight yet high strength-to-weight ratio.
• Performance
Continuous operation at 125°C (intermittent 150°C), pressure rating 42 MPa. Low permeation (<0.1g/m²/day per ISO 17491).
• Fluid Compatibility
Compatible with synthetic esters, HFD-R fluids, and aggressive hydraulic oils.
• Environmental Suitability
Non conductive, ideal for high-temperature industrial systems (e.g., steel mills). Meets EN 857 2SC, DIN 20023.
Key Applications
• Anchor Windlasses
Reliable hydraulic power for marine mooring systems
• Submarine Control Systems
High integrity hoses for underwater vessels
• Tractor Hydraulic Lift Systems
Agricultural implement control
• Combine Harvester Drives
Contamination-resistant hydraulic lines
FAQ
1. What is the burst pressure of a hydraulic hose?
Burst pressure is typically 4 times the working pressure but depends on hose construction and standard.
2. Can I cut hydraulic hose to length?
Yes, but it must be cut cleanly and fitted with appropriate couplings using proper equipment.
3. What is the bend radius, and why is it important?
It’s the minimum radius a hose can bend without damage. Exceeding it may cause kinks or reduced lifespan.
4. What are the signs of hydraulic hose failure?
Cracks, leaks, bulging, abrasions, and reduced system pressure are typical indicators.
