Component Specifications

Definition
Hydraulic lines (hoses or pipes) and connectors (fittings, couplings) form a sealed network that conveys hydraulic fluid from the pump to actuators (e.g., cylinders) in machinery attachments. They maintain system pressure integrity, withstand dynamic loads, and ensure precise fluid flow for operations such as lifting, digging, or tilting in industrial equipment.
Working Principle
Operate based on Pascal's law, transmitting fluid pressure through lines to generate mechanical force at actuators. Connectors ensure leak-proof joints, while lines accommodate movement and vibration without compromising pressure or flow rates.
Materials
High-strength synthetic rubber (e.g., NBR, HNBR) or thermoplastic (e.g., PA, PTFE) for hoses; steel (e.g., carbon steel, stainless steel) or brass for fittings; seals made of nitrile, fluorocarbon, or polyurethane.
Technical Parameters
  • Size Range 1/4" to 2" diameter
  • Burst Pressure 4x working pressure
  • Pressure Rating Up to 5000 psi
  • Temperature Range -40°C to 120°C
  • Fluid Compatibility Hydraulic oils, water-glycol
Standards
ISO 18752, ISO 12151, DIN 20066, SAE J517

  • Connector failure resulting in attachment malfunction
  • Material degradation from chemical exposure or UV radiation
FMEA Triads
Trigger: Abrasion from contact with sharp edges or moving parts
Failure: Hose wear and eventual rupture
Mitigation: Use protective sleeves, proper routing, and regular inspections
Trigger: Improper installation (e.g., over-tightening fittings)
Failure: Thread damage or seal compression failure leading to leaks
Mitigation: Follow torque specifications and use correct tools during assembly

Frequently Asked Questions

How often should hydraulic lines be inspected?

Inspect visually before each use and perform detailed checks every 250-500 operating hours or as per manufacturer guidelines to detect wear, leaks, or damage.

Can hydraulic connectors from different brands be interchanged?

Only if they meet identical specifications (e.g., thread type, pressure rating, size); mixing incompatible brands can cause leaks or system failure.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
