803420513 XCMG GR2605 motor grader hose assembly

803420513 XCMG GR2605 motor grader hose assembly

803420513 is the original high-pressure hydraulic hose assembly for the XCMG GR2605 grader. It’s used for flexible oil circuit connections in the hydraulic system, offering pressure resistance, vibration resistance, and aging resistance to ensure stable and reliable hydraulic operation.

Core Functions and Roles

Flexible connection to hydraulic pumps, valve blocks, cylinders, and other components, delivering high-pressure hydraulic oil to ensure smooth machine operation.

Absorbing vibrations, impacts, and thermal expansion and contraction during equipment operation, preventing cracking of rigid pipes and oil leakage due to loose joints.

Original assembly crimping process ensures excellent sealing performance, preventing leakage even under high pressure and pulse conditions.

Oil-resistant, aging-resistant, and wear-resistant, suitable for complex environments such as construction site dust, mud, and high and low temperatures.
