Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C2, Citroën C3, Citroën C3 Pluriel
- Product Codes: 9650823380, 6460ZR, 647794
- Additional Numbers: 9650823380 647794 6460ZR NFP
Function
The A/C pipe transports refrigerant between components of the air conditioning system (compressor, condenser, dryer/receiver and evaporator). It ensures sealed, pressure-rated flow and supports refrigerant oil circulation necessary for compressor lubrication. Proper integrity of the pipe and its connections is essential for cooling efficiency and system longevity.
Common Failure Causes
- Corrosion and Rust: Exposure to road salt and moisture can perforate metal sections or fittings.
- Mechanical Damage: Impact or vibration can cause dents, cracks or fractured fittings.
- O-Ring Degradation: Hardened or missing seals at connection points lead to refrigerant and oil leaks.
- Chafing And Abrasion: Contact with other components or mounting points wears the pipe through.
- Contamination: Debris from a failed compressor or corroded parts accelerates deterioration and clogs lines.
Installation Recommendations
- Recover Refrigerant Legally: Always evacuate and recover refrigerant using certified equipment before disassembly.
- Replace Seals: Fit new O-rings of the correct size and material; lubricate with the specified refrigerant oil during assembly.
- Inspect Related Components: Check Condenser, Receiver/Drier, Compressor and Hoses for contamination or damage; replace receiver/drier when the system is opened for repair.
- System Evacuation And Recharge: Perform vacuum, leak test and recharge with the correct refrigerant type and oil quantity as per manufacturer specifications.
- Leak Test And Functional Check: Pressure-test and run the system to verify cooling performance and absence of leaks before returning vehicle to service.
- Professional Handling Recommended: Refrigerant handling and system charging should be carried out by trained personnel with appropriate service tools and certification.
Why Replace The Pipe
Customers typically replace the A/C pipe because of visible leaks (oil traces or refrigerant hissing), loss of cooling capacity, or after component failures that contaminate the circuit. Replacing the damaged pipe and renewing seals restores system pressure integrity and prevents recurrent losses.
Search And Identification Tips
Technicians and DIYers frequently search by the OEM numbers 9650823380, 6460ZR or 647794. Confirm fitment visually against the original routing and connection types. When replacing, ensure matching connection diameters and mounting points to avoid installation issues.
