803422530 XCMG GR2605 motor grader hose assembly

Specialized pressure-resistant connecting hoses for hydraulic systems in construction machinery, suitable for pipeline transmission, pressure circulation, and other operating conditions, used for hydraulic circuit connections and sealing.

Core Functions

Pressure Transmission: Withstands the normal pressure of the hydraulic system, achieving stable oil transmission, suitable for hydraulic circuits in construction machinery.

Shock Absorption and Buffering: Absorbs vibration and impact during equipment operation, reducing pipeline stress concentration and minimizing component wear.

Sealing Connection: Precise fit between the connectors at both ends and the pipeline prevents oil leakage and ensures system sealing performance.

Flexibility: Possesses a certain degree of flexibility, adaptable to the installation layout of articulated and moving parts in equipment.

Suitable Scenarios

Excavator, loader, and construction machinery hydraulic systems, used for the transmission of hydraulic oil, water, and other media, suitable for various articulated and moving component connections.

Technical Features

Material: High-strength synthetic rubber + reinforced steel wire layer, wear-resistant, fatigue-resistant, and aging-resistant.

Compatible with: 803, 105, 653, and other connector series; easy to install.

Troubleshooting: Operating range -40℃ to +100℃

Common Problems

Hoses cracking, connector leaks, outer layer damage, pressure leaks.
Troubleshooting: Check the overall appearance, connector sealing surfaces, and pipe bending angles; replace immediately if abnormal.

wear and deformation, check the fit clearance, and judge the condition based on abnormal operating noises. If abnormal, stop use immediately and replace the pin.
