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 Part
    Flexible conduit that transports hydraulic fluid while accommodating movement and vibration
    Material: Synthetic rubber with steel wire reinforcement
  • End Fittings Part
    Provide secure, leak-proof connections to hydraulic system components
    Material: Steel or stainless steel
  • Crimp Sleeve Part
    Mechanically attaches fittings to the hose through compression
    Material: Steel

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 5,000 psi (standard), burst pressure typically 4x working pressure
flow rate: Dependent on hose ID and fluid viscosity, typically 1-100 GPM range
temperature: -40°C to +100°C (standard), up to +120°C with special compounds
slurry concentration: Not recommended for abrasive slurries >5% solids by volume
Media Compatibility
✓ Hydraulic oil (mineral-based) ✓ Water-glycol fluids ✓ Synthetic ester fluids
Unsuitable: Chlorinated solvents or strong oxidizing acids
Sizing Data Required
  • System working pressure (psi)
  • Required flow rate (GPM)
  • Hose routing/bend radius requirements

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive wear
Cause: Contaminant particles in hydraulic fluid causing internal erosion of hose lining and fittings
Flex fatigue failure
Cause: Improper routing causing excessive bending or twisting beyond hose minimum bend radius
Maintenance Indicators
  • Visible external cracking, blistering, or abrasion on hose cover
  • 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
