Application And Fitment
Fits the air conditioning systems of the listed Peugeot and Citroën models when specified by the above product codes. Always confirm the part number stamped on the original pipe before ordering to ensure correct routing and connection type (flare/quick-fit). Fitment can vary by model year and engine/trim; match 9684310980 / 6477G6 to the vehicle’s existing refrigerant line.
Function
The pipe carries refrigerant between components of the vehicle air conditioning system (compressor, condenser, dryer/receiver, evaporator). It maintains sealed, high- and low-pressure pathways required for correct heat exchange. Proper sealing at connection points with new O-rings is essential to prevent refrigerant loss and to keep system oil circulation intact.
Replacement Guide
- Recover Refrigerant: The A/C system must be evacuated and refrigerant recovered using certified equipment according to local regulations.
- Access and Remove: Remove any engine covers, brackets or components obstructing the pipe. Unbolt fittings and carefully separate connections to avoid damaging mating parts.
- Replace Seals: Always fit new O-rings/seals lubricated with the correct PAG oil. Do not reuse old seals.
- Vacuum And Refill: Evacuate the system to the correct vacuum level, perform a leak check, then recharge with the specified refrigerant charge and oil quantity.
- Leak Test And Function Check: Pressure-test the system and verify proper cooling and compressor operation before returning the vehicle to service.
Installation Recommendations
- Use Proper Tools: Employ correct A/C disconnect tools, torque settings and a calibrated vacuum/recharge station.
- Replace Related Items: Consider replacing O-rings, service port caps and, if contaminated, the receiver/drier or accumulator when opening the system.
- Health And Safety: Wear protective gloves and safety glasses. Work in a well-ventilated area and follow environmental rules for refrigerant handling.
- Professional Service Recommended: If you are not equipped to recover and recharge refrigerant, have the job completed by an authorized workshop.
Common Reasons For Failure
- Corrosion And Wear: Exposure to road salt, moisture and heat cycles causes metal fatigue or corrosion at bends and joints, leading to leaks.
- Mechanical Damage: Impact from debris or improper routing during repairs can kink or crack the pipe.
- Seal Degradation: O-rings and sealing surfaces deteriorate with age and thermal cycling, becoming the primary leak points.
- System Contamination: Debris or moisture inside the A/C can accelerate corrosion and damage internal components that place extra strain on lines.
Replacing the pipe with a correctly specified unit and following recommended installation practices restores reliability and prevents refrigerant loss, saving time and cost compared to repeated leak repairs.
