• Function 

1. Fluid Conveyance
Function: Transports hydraulic oil, coolant, or fuel between different parts of the machine.
Working Principle: The hose’s inner tube is made from materials resistant to the specific fluid it carries, ensuring compatibility and preventing leaks. The fluid enters the hose at one end and is directed to its destination under pressure or gravity.
Importance: Maintains the continuous flow of essential fluids, enabling systems like hydraulics, cooling, and fuel delivery to operate properly.

2. Pressure and Temperature Resistance
Function: Withstands high operating pressures and extreme temperatures.
Working Principle: Constructed from durable materials, such as synthetic rubber or thermoplastic, reinforced with layers of fabric or metal braiding to enhance strength and flexibility.
Importance: Ensures the hose remains intact under the demanding conditions of heavy machinery operation, preventing bursts or failures that could lead to fluid loss or system damage.
