712W15204-0025 Metal Hose Assembly

This metal hose assembly is a flexible connection conduit used to convey various media (such as fuel, lubricating oil, hydraulic oil, compressed air, etc.). Its core function is to provide a reliable and durable connection between fixed and moving components, while compensating for vibration, displacement, and thermal expansion/contraction.

Function

1. Compensate for Displacement and Vibration

The inherent flexibility of the hose absorbs and compensates for positional changes in piping caused by engine vibration, vehicle movement, or equipment operation, preventing stress fatigue and potential failure in rigid connections.

2. Withstand High Pressure and Temperature

The metal material (often stainless steel) enables it to withstand high working pressures and extreme temperatures, offering stable performance and long service life.

3. Corrosion and Abrasion Resistance

The metal hose offers excellent resistance to oil, chemical corrosion, and abrasion, making it suitable for harsh operating environments.

4. Noise Reduction and Misalignment Tolerance

The flexible structure helps dampen noise generated by fluid pulsation and vibration transmission, and can tolerate minor installation misalignments.

Primary Applications

Primarily used to connect vibrating components (like the engine, transmission, axles) to fixed pipelines on the vehicle frame.

Suitable for high-pressure fuel systems, turbocharger pipelines, hydraulic systems, and other applications demanding pressure and temperature resistance.

Commonly used in locations prone to exposure to mud, salt, or other corrosive substances, such as under the chassis.

Improves driving comfort and simplifies the installation process.

In summary, its primary application is to provide a robust, durable, and reliable flexible connection solution for pipeline systems in trucks where relative motion, vibration, or high temperature/pressure conditions exist.
