Application and Function in the Air Conditioning System

This hose belongs to the Air Conditioning Hoses, Pipes, and Connectors group, responsible for safely and securely routing refrigerant between key system components. For the F10/F11 LCI 5 Series with the B47 unit, a correctly selected hose is crucial for:

• maintaining proper pressure in the air conditioning circuit,
• minimizing refrigerant and oil loss,
• stable operation of the compressor and control valves,
• preserving the factory interior cooling performance.

The hose's appropriate stiffness and flexibility translate to resistance against vibrations generated by the B47 engine and long-term connection durability.

Original Origin and BMW Fitment

This part comes from the BMW line, meaning it adheres to factory manufacturing standards, connection diameters, and a shape precisely fitted to the F10/F11 LCI engine bay. Original connectors ensure proper integration with other air conditioning system components without the need for modifications or adapters.

This precise fitment reduces the risk of stress on the ports, minimizes the possibility of micro-leaks, and simplifies servicing – both during installation and for any future diagnostic work.

Characteristics of the Used Component

The hose is offered as a used original part, allowing you to combine factory fitment with a more favorable cost compared to a new part. For many F10/F11 LCI 5 Series owners, this is a sensible solution for air conditioning system repairs, especially when aiming to maintain the vehicle's original specifications.

Choosing an original part from disassembly is particularly important where the air conditioning system operates under high pressure and requires the preservation of appropriate material quality and manufacturing precision.
