Application and Function in the Air Conditioning System

The offered hose belongs to the Air Conditioning Hoses, Pipes, and Connectors category and is responsible for transporting refrigerant between individual air conditioning components. A correctly selected hose or pipe is crucial for:

• maintaining the refrigerant circuit's seal,
• stable operating pressure in the system,
• reducing vibrations and stresses in connections,
• seamless cooperation with the compressor, condenser, and evaporator.

Properly matching the hose to a specific E90, E90N, E91, or E92 body version allows for maintaining the air conditioning's factory operating characteristics and avoiding leaks resulting from imprecise installation.

The hose comes from the BMW line, meaning it complies with the factory quality and dimensioning standards used by the manufacturer. The part has a dedicated OEM part number and assigned replacement numbers, making it easy to verify with the BMW catalog or service software and match it to a specific vehicle configuration.

Thanks to the presence of reference numbers, the hose can replace several factory variants, simplifying selection for upgrades or repairs of the air conditioning system in various E9x 3 Series trim levels.

Condition, Selection, and Practical Application in Service

The item is offered in used condition, which in workshop practice means the possibility of economical repair of the air conditioning system while maintaining the original manufacturer's specifications. This type of hose is particularly useful when:

• the existing pipe has suffered mechanical damage (corrosion, cracking, abrasion),
• a section of the system needs replacement after a collision or bodywork intervention,
• you want to restore air conditioning functionality without resorting to aftermarket parts of uncertain parameters.

Before installation, standard service procedures are recommended: checking system tightness, replacing seals at connection points, and performing a pressure test after assembly. This approach allows for fully utilizing the potential of the original hose and minimizing the risk of further system intervention.
