Description
Air Conditioning Pipe for Peugeot 308, 3008, 5008, RCZ Citroën C4, C4 Picasso
This Air Conditioning Pipe is an OEM-fit part for a range of Peugeot and Citroën models and is identified by part codes 9684310980 and 6477G6. Designed for professional workshops and competent DIY mechanics, the pipe restores proper refrigerant flow in the A/C system and helps return system performance and reliability to factory standards. The component is a direct replacement for the original line routed between the condenser/evaporator and other A/C system elements, ensuring correct fitment and routing without the need for major modifications.
Key benefits for the workshop: straightforward fitment for compatible models, time savings compared with fabricated repairs, and elimination of leak points associated with damaged or corroded original pipes. The pipe is particularly useful when diagnosing low cooling performance, visible oil traces, or when replacing other A/C components where disturbing the original line is unavoidable.

Installation Recommendation
Replacement of an A/C pipe requires basic A/C service equipment and adherence to safety and environmental regulations. Recommended workflow:
- Recover refrigerant using certified A/C recovery equipment and follow local legal requirements.
- Gain access to the damaged pipe (may require removal of undertrays, engine covers or front bumper depending on model).
- Remove clamps and fittings, keeping track of all seals and brackets.
- Replace all O-rings and sealing washers at connections with new ones lubricated with the correct compressor oil per manufacturer specification.
- Install the new pipe, secure clamps to specified torque, and ensure correct routing to avoid contact with hot or moving parts.
- Evacuate the system (deep vacuum) to remove moisture and check for leaks using a calibrated leak detector or pressure test.
- Recharge the system to the manufacturer’s specified refrigerant charge and oil quantity, then perform a performance check.
Always wear appropriate personal protective equipment and follow workshop safety rules. If any electronic sensors or components are removed during access, observe manufacturer handling instructions.
Why This Part Fails Most Often
- Corrosion and Galvanic Attack: Road salt and moisture can corrode metal lines, especially at joints and bends, causing leaks.
- Mechanical Damage: Impact from road debris or accidental contact during repairs can dent or rupture the pipe.
- Vibration And Chafing: Improper routing or failed mounting clips allow the pipe to rub against chassis parts, leading to wear-through.
- Aging Seals: O-Rings and connectors harden with time and heat, creating leak paths at flanged joints.
- Contamination: Debris in the system or oil degradation can accelerate wear and clog small passages, stressing pipe connections.
