Product Specifications

Technical details and manufacturing context for Hydraulic Hose Assembly

Definition
A hydraulic hose assembly is a critical component within hydraulic extensions that connects various hydraulic system elements, enabling the transmission of pressurized hydraulic fluid between pumps, valves, actuators, and other components. It consists of a flexible hose reinforced with layers of braided wire or textile, permanently attached to metal fittings at both ends to ensure leak-proof connections.
Working Principle
Hydraulic hose assemblies transmit hydraulic fluid under pressure from one component to another in a hydraulic system. The flexible hose accommodates movement and vibration while maintaining structural integrity under high pressure, with the fittings providing secure connections that prevent fluid leakage and maintain system pressure.
Common Materials
Synthetic rubber (inner tube), Steel wire reinforcement, Weather-resistant rubber cover, Steel fittings
Technical Parameters
  • Inner diameter of the hose, typically ranging from 6mm to 50mm depending on flow requirements (mm) Customizable
Components / BOM
  • Hydraulic Hose
    Flexible conduit that transports hydraulic fluid while accommodating movement and vibration
    Material: Synthetic rubber with steel wire reinforcement
  • End Fittings
    Provide secure, leak-proof connections to hydraulic system components
    Material: Steel or stainless steel
  • Crimp Sleeve
    Mechanically attaches fittings to the hose through compression
    Material: Steel
Engineering Reasoning
0-350 bar (0-35 MPa) with burst pressure at 4:1 safety factor (1400 bar/140 MPa)
Hose rupture occurs at 1400 bar (140 MPa) internal pressure or 125°C continuous operating temperature
Design Rationale: Polymer chain scission in synthetic rubber reinforcement layers due to cyclic pressure-induced tensile stress exceeding 21 MPa yield strength
Risk Mitigation (FMEA)
Trigger Fluid contamination with particulate matter exceeding ISO 4406 18/16/13 cleanliness level
Mode: Abrasive wear of inner tube causing 0.5 mm/year material loss and hydraulic fluid leakage
Strategy: Install 10 μm absolute filtration with differential pressure monitoring at 3 bar threshold
Trigger Ultraviolet radiation exposure exceeding 1000 W/m² for 2000 hours
Mode: Polymer oxidation reducing hose flexibility by 40% and causing crack propagation at 0.1 mm/min rate
Strategy: Apply carbon-black reinforced chloroprene rubber sheath with 3 mm minimum thickness

  • Audible hissing or visible fluid spray indicating pressure leaks
Engineering Tips
  • Implement proper hose routing with adequate bend radius and protection from abrasion points
  • Maintain fluid cleanliness through regular filtration and use compatible fluids to prevent chemical degradation

Compliance & Manufacturing Standards

Reference Standards
ISO 18752:2017 - Rubber hoses and hose assemblies for hydraulic applications ANSI/SAE J517 - Hydraulic Hose DIN EN 853 - Rubber hoses and hose assemblies for hydraulic applications
Manufacturing Precision
  • Bore diameter: +/-0.02mm
  • Length tolerance: +/-1% of nominal length
Quality Inspection
  • Pressure test: 1.5x working pressure for 2 minutes
  • Visual inspection for surface defects and proper crimping
