Supplied with the referenced OEM numbers, it is intended for vehicles using the original piping layout and mounting points.

Key Benefits

• Direct fit to original routing for clean installation and secure mounting.
• Reduces the number of connection points compared with individual pipes, lowering the risk of leaks when properly installed.
• OEM cross-reference numbers included for fast identification: ideal when searching by part number (9686414180, 9659576380, 6477F2, 647774).
• Made for professional garages and experienced DIYers who handle AC system service and refrigerant recovery.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C5 X7 (2009, 3.0 HDi)
• Product Codes: 9686414180, 9659576380, 6477F2, 647774
• Other Numbers: 647774, 6477F2, 9659576380, 9686414180

Function And Typical Location

This pipe carries refrigerant between air conditioning components (compressor, condenser, evaporator/expansion valve) and is routed under the bonnet and along chassis/body fixing points depending on the vehicle layout. In this assembly two lines are joined together to match the vehicle’s factory routing and mounting brackets.

Common Failure Modes

Air conditioning pipes most often fail due to corrosion, mechanical damage, or degradation of sealing elements. Frequent causes include:

• Corrosion from road salt and moisture on metal lines and fittings.
• Stone strikes, abrasions, or impact damage from road debris.
• Fatigue at connection points or bends caused by vibration and engine movement.
• O-Ring deterioration at mating joints leading to refrigerant and oil leaks.

Replacement And Installation Recommendations

Replacement of an AC pipe requires correct refrigerant handling and basic air conditioning service equipment. Recommended procedure:

• Recover Refrigerant: Recover the system refrigerant using certified recovery equipment (the 2009 C5 typically uses R134a systems).
• Remove Old Pipe: Remove clamps and fittings; inspect surrounding components for damage and clean mating surfaces.
• Replace Seals: Replace all O-rings and seals with correct size and material (lubricate with correct PAG oil compatible with the system).
• Install New Pipe: Fit the new pipe in the factory routing, secure all clamps and brackets, and torque fittings to manufacturer values where available.
• Vacuum And Refill: Evacuate the system to remove moisture, then charge with the specified refrigerant charge and oil volume per manufacturer specification.
• Leak Test And Function Check: Perform a pressure/leak test and verify system pressures and cooling performance after commissioning.

Because refrigerant handling is regulated and requires special equipment, this job is recommended for professional workshops or experienced technicians with the required tools and certification.

Why Replace The O-Rings And Inspect Surroundings

Even if the pipe body is intact, aged O-rings often cause slow leaks and should always be renewed during replacement. Inspect adjacent components (compressor, condenser, drier/accumulator, expansion valve) for signs of oil or refrigerant traces that indicate secondary damage.

Notes For Buyers

Searches for this part are frequently performed by the OE numbers listed above. If you are a mechanic or a competent DIYer familiar with AC service, this pipe offers a direct-fit solution for the specified Citroën C5 application and compatible Stellantis models that share the same part references.

Installation Recommendations

• Have Refrigerant Recovered: Always recover refrigerant with appropriate equipment before opening the A/C system. This must be performed in accordance with environmental and safety regulations.
• Replace Seals And Lubricant: Fit new O-rings and apply correct PAG oil compatible with the vehicle’s system to prevent leaks and ensure proper lubrication.
• Use Correct Tools And Procedure: Remove any obstructing trim or covers, loosen clamps or connections at the designated joints, separate the two-piece assembly if required, and install the replacement pipe ensuring clean mating surfaces.
• Vacuum And Recharge: After fitting, evacuate the system to remove moisture and air, then recharge to the manufacturer-specified refrigerant charge and pressure.
• Leak And Function Test: Perform a pressure/leak test and run the A/C to verify correct operation and cooling performance.
• Professional Service Recommended For Refrigerant Handling: Recovery, evacuation, and recharge are recommended to be done by a qualified workshop with proper A/C service equipment.

Why This Part Fails Most Often

• Corrosion And Environmental Damage: Exposure to road salt and moisture causes corrosion at joints and fittings, leading to leaks over time.
• Mechanical Impact: Stone chips, debris, or improper handling during repairs can dent or crack the lines.
• Ageing Seals: O-rings and seals harden or deteriorate with heat cycles, causing refrigerant leaks at connection points.
• Vibration And Fatigue: Continuous vibration can weaken crimped joints or connections, especially on older vehicles.
