Description
Air conditioning refrigerant pipe for CITROËN C5 II and PEUGEOT 407
This air conditioning refrigerant pipe is a direct replacement line designed for Citroën C5 II and Peugeot 407 models. Frequently searched by OE numbers, it fits original system layouts and restores proper refrigerant routing when the factory line is damaged or leaking. Suitable for professional workshops and experienced DIY mechanics, this pipe helps recover AC performance, reduce refrigerant loss and prevent compressor damage caused by low charge or contamination.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C5 II, Peugeot 407
- Product Codes: 9650885580, 6460LP
- Other Numbers: NFP
Recommended Installation
Replacement should be performed by a qualified technician or an experienced DIY mechanic with the correct tools. Recommended steps:
- Recover Refrigerant Using Approved Equipment: Always evacuate refrigerant to compliant recovery equipment before opening the system.
- Remove Damaged Line: Unbolt fittings and carefully remove the old pipe, taking note of routing and bracket positions.
- Replace Seals and O-Rings: Fit new O-rings/seals treated with the correct PAG oil or lubricant specified for the system.
- Install New Pipe: Re-fit the pipe, secure all brackets, and torque fittings to manufacturer specifications where available.
- Pressure Test And Evacuate: Perform a vacuum test to ensure tightness, then leak-check under pressure before recharging.
- Recharge System: Refill with the correct type and amount of refrigerant and oil per vehicle specification, then verify operation and temperatures.
Why This Part Fails Most Often
Common causes of failure include corrosion from road salt and moisture, mechanical damage from impacts or worn mounting brackets, vibration fatigue at connection points, and degradation of seals and O-rings leading to slow leaks. External rubbing against other components or improper routing after previous repairs may also cause premature wear.
Signs Of Fault And Practical Tips
Typical symptoms indicating a leaking or blocked AC pipe are reduced cooling efficiency, visible oil or refrigerant stains on the line or fittings, audible hissing, and a compressor that cycles frequently or fails to build pressure. When replacing the pipe, always inspect adjacent components (compressor, condenser, evaporator, and dryer/accumulator) because contamination or loss of oil can accelerate wear elsewhere in the system.
Notes For Search And Compatibility
Customers often locate this part by OE numbers 9650885580 or 6460LP. Ensure the replacement matches the original routing and connector types on Citroën C5 II and Peugeot 407 model years to guarantee fitment.
