380901220 XCMG GR2605 motor grader rubber hose φ16

380901220 XCMG GR2605 motor grader rubber hose φ16

380901220 is a dedicated φ16 hose from the XCMG GR2605 grader, used for hydraulic, cooling, and fluid media transportation. It features pressure and oil resistance, vibration and wear resistance, and reliable sealing, making it suitable for harsh working conditions in construction machinery and ensuring stable operation of the pipeline system.

Core Functions and Roles

Media Transportation: Precisely transports core media such as hydraulic oil, coolant, and antifreeze. It conforms to the φ16 pipe diameter standard, meeting the flow requirements of the equipment’s hydraulic and cooling systems.

Shock Absorption and Vibration Resistance: The flexible rubber structure absorbs vibrations from equipment operation, reducing pipeline stress, preventing joint loosening and pipeline cracking, and adapting to high-intensity vibration conditions.

Sealing and Protection: The multi-layer composite structure design effectively prevents media leakage, blocks dust, oil, and moisture intrusion, and protects the pipeline and surrounding precision components.

Deformation Compensation: Adapts to thermal expansion and contraction of the pipeline and equipment displacement, absorbs installation errors, avoids pipeline twisting and bursting, and extends system service life.
