Description
Air Conditioning Pipe For CITROËN C2, C3 And C3 Pluriel
Product Overview
This air conditioning pipe is suitable for Citroën small‑car platforms and is commonly referenced by part numbers 9650823380, 6460ZR and 647794. It is designed to route refrigerant between AC components and restore the integrity of the cooling circuit after damage or wear. Ideal for professional workshops and experienced DIYers looking for a direct replacement that matches original fitment on the listed models.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C2; Citroën C3; Citroën C3 Pluriel
- Product Codes: 9650823380; 6460ZR; 647794
- Other Numbers: NFP
Function And Typical Construction
The pipe carries refrigerant under pressure between AC components (for example between the evaporator, compressor and condenser), and includes dedicated fittings and sealing interfaces. Construction is metal tubing (commonly aluminum) with service connection points and rubber O‑ring seals. Proper sealing and routing are critical to maintain system pressure and prevent leaks.
Replacement Procedure (Summary For Mechanics And Experienced DIY)
- Safely recover refrigerant from the system using certified recovery equipment before any disassembly.
- Access the pipe by removing any relevant trim or underbody shields to reach the AC lines and fittings.
- Loosen and disconnect the pipe connections at the designated service ports or flared fittings. Inspect mating surfaces.
- Replace all O‑rings/seals with new, correctly sized parts lubricated with the manufacturer‑specified AC oil.
- Fit the replacement pipe and tighten connections to manufacturer specifications where available; avoid overtightening.
- Evacuate the system to remove moisture and check for leaks (vacuum test), then recharge with the correct type and amount of refrigerant and oil per manufacturer specifications.
- Perform a functional test of the air conditioning system and recheck for leaks after a short test drive.
Installation Recommendations
- Always use professional refrigerant recovery and charging equipment; venting refrigerant to atmosphere is illegal and harmful.
- Replace sealing O‑rings whenever a line is disconnected and lubricate them with the specified compressor oil to ensure proper sealing.
- Inspect nearby lines, brackets and mounting points for corrosion or damage and secure any loose clamps to prevent future chafing.
- After installation perform a vacuum and leak test, then charge the system to the exact refrigerant and oil specifications for the vehicle (many pre‑2017 PSA models use R134a—confirm against vehicle documentation before service).
- If in doubt or lacking AC service equipment, have the job completed by an authorized workshop to ensure system integrity and safety.
Why This Part Fails Most Often
AC pipes commonly fail due to corrosion from road salt and moisture, impact or abrasion from road debris, vibration‑induced fatigue at brackets or fittings, and seal deterioration (O‑rings) leading to slow leaks. Improper previous repairs, over‑tightening of fittings or prolonged refrigerant/oil loss can accelerate wear and cause complete loss of cooling performance.
Notes For Buyers
Searches for this part are often performed using the product numbers 9650823380, 6460ZR or 647794—including these codes in your search will help locate the correct item quickly. The part is intended for Citroën C2, C3 and C3 Pluriel models; ensure visual match with the existing pipe and fittings before installation.
