Core Functions and Roles

This component enables flexible connections, compensating for pipeline displacement, vibration, and coaxiality deviations during equipment operation, absorbing hydraulic shock, reducing pipeline stress, and protecting hydraulic components. Its core function is to stably deliver hydraulic oil, coolant, and other key media, ensuring the normal operation of the hydraulic and cooling systems without leakage. It also provides shock absorption and noise reduction, effectively attenuating vibrations and noise generated during equipment operation, improving equipment stability, and reducing component wear. The multi-layer steel wire reinforcement structure provides pressure and impact resistance, enabling it to withstand high-pressure conditions and operational impacts, preventing hose bursts and damage. The outer wear-resistant rubber material is suitable for complex outdoor construction environments such as dust, oil, and humidity, effectively extending the component’s service life.

Suitable Applications

Primarily used for connecting the hydraulic, cooling, and pneumatic systems of construction machinery such as bulldozers, excavators, loaders, and road rollers. Suitable for heavy-duty applications such as earthwork, infrastructure construction, mining, and road building, it is a core component for flexible connections in the equipment’s hydraulic circuit.
