Intended Use and Function in the Air Conditioning System

This hose belongs to the Air Conditioning Hoses, Pipes, and Connectors group, responsible for transporting refrigerant between individual system components. The correct geometry and diameter of the hose are crucial for:

• maintaining adequate working pressure in the system,
• ensuring leak-free connections with the compressor, condenser, or evaporator,
• limiting pressure drops and air conditioning performance losses,
• stable operation of valves and pressure sensors.

Choosing a hose dedicated to the Porsche 911 generation 996 helps avoid problems with incorrect length, diameter, or connector types, which directly impacts the trouble-free operation of the air conditioning system.

Original Origin and Fit for Porsche

This part comes from the Porsche brand, meaning it complies with factory technical documentation and parameters specified by the vehicle manufacturer. The original air conditioning hose for the 911 996 ensures:

• compatibility with factory mounting brackets and installation routing in the body,
• correct positioning relative to other components in the engine bay and undercarriage,
• maintenance of the refrigerant flow path designed by the manufacturer.

This allows for predictable installation without the need for modifications, and the system retains its operating characteristics in line with Porsche's design intentions.

Performance Characteristics and Item Condition

The offered air conditioning hose is marked as used, allowing for economical system repair while maintaining the original part specifications. In practice, this means the possibility of:

• restoring system integrity after mechanical damage or corrosion of the old hose,
• reducing service costs compared to purchasing a new OEM component,
• maintaining the air conditioning system's consistency with other factory components.

Choosing an original, used hose is particularly beneficial for daily driven vehicles where both correct air conditioning operation and a rational approach to repair budgets are important.

Integration with Other Air Conditioning Components

The air conditioning hose in the Porsche 911 996 works with other system components such as the compressor, condenser, dryer, and evaporator. The correct fit of the hose affects:

• even distribution of refrigerant throughout the entire circuit,
• stable compressor operation without excessive loads,
• efficient heat dissipation in the condenser,
• maintaining the correct cabin air temperature.

In case of system intervention – e.g., after a collision, compressor replacement, or condenser replacement – using the correct hose helps avoid leaks, hose vibrations, or improper positioning relative to body components.

Technical Support and Additional Information

To facilitate part identification, the hose is assigned OEM numbers and interchangeable numbers, allowing for precise matching to a specific Porsche 911 996 configuration. If in doubt, it is advisable to compare the markings with the vehicle's documentation or the numbers found on the removed hose.
