382300167 XCMG GR2605 motor grader housong hydraulic pipe laying

382300167 Rear-mounted hydraulic piping is a flexible conveying pipe specifically designed for rear-end release/return/auxiliary oil circuits in engineering machinery hydraulic systems. It features a reinforced fabric structure, is suitable for low-pressure hydraulic media delivery, and ensures flexible pipeline layout, reliable sealing, and oil resistance and durability.

Core Functions and Roles

Hydraulic Media Delivery: Adapts to the rear oil circuits of engineering machinery hydraulic systems, delivering hydraulic oil, emulsions, and other media to achieve fluid connection and circulation between hydraulic components.

Flexible Piping Adaptability: Adapts to complex rear-end space layouts of equipment, offering good flexibility, reducing pipeline interference, and simplifying installation and maintenance.

Oil-Resistant Sealing Protection: The inner rubber layer is resistant to hydraulic oil corrosion, and the outer rubber layer is resistant to oil stains and aging, ensuring long-term stable sealing and preventing media leakage.

Low-Pressure Condition Adaptability: Specifically designed for low-pressure hydraulic circuits, providing stable pressure resistance and meeting the non-high-pressure transmission requirements of return, release, and auxiliary oil circuits.
