The hose construction combines flexible and rigid sections, which allows for compensation of engine unit vibrations and minimizes the risk of micro-cracks at critical points in the system.
Key technical advantages include:
- factory fit for the air conditioning system in the Mercedes C-Class W205 generation,
- use of materials resistant to refrigerant and compressor oil,
- a hose routing path designed by the manufacturer, reducing the risk of abrasion and collision with other components.
Component Condition and Installation Aspects
The offered hose is a used original component from disassembly and is classified as a used original component. This type of part allows for economical repair of the air conditioning system while maintaining the factory installation specification. In practice, this means the possibility of restoring the original system configuration without the need for adapters or modifications.
During installation, it is recommended to:
- check the condition of the sockets and connectors in the vehicle before installing the hose,
- use new seals at connection points,
- perform a leak test and the correct vacuuming and filling process of the system after completion of work.
Why Choose an Original Mercedes Hose
