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.
