Description
Air conditioning pipe for PEUGEOT 308, 3008, 5008, RCZ and CITROEN C4, C4 II, C4 PICASSO cars
Part description
This Citroën Peugeot air conditioning pipe is a used original part intended for the vehicles listed in the documents. It is an important part of the air conditioning circuit, which ensures the conduction of the refrigerant between the individual elements of the system. When looking for the right part, the product number is often decisive, so we recommend comparing the markings 9684755680 and 6477H8 with the disassembled piece.
Climate pipes are often stressed by vibrations, temperature changes and the age of the material. If the original pipe is damaged, leaking or mechanically deformed, replacing it with a suitable part is important for the correct operation of the air conditioner and the restoration of the system tightness.

Installation recommendations
Generally/typically for this type of part, the exact replacement procedure depends on the specific model and make of the car. It is necessary to work professionally with parts of the air conditioning system and with regard to the tightness of the circuit.
1) Before assembly
- Check whether the used pipe matches the old part in shape, length, routing, attachment and ends.
- Check carefully whether the air conditioning pipe is dented, cracked, excessively corroded or otherwise mechanically damaged.
- Check the seating surfaces and the condition of the sealing points.
- Compare product numbers 9684755680 and 6477H8 with the original part.
- If the system has been leaking for a long time, it is also advisable to check the surrounding parts of the air conditioning circuit.
2) Necessary tools and materials
- Common workshop hand tools
- Suitable tools for removing covers and brackets
- Clean lint-free cloths
- New gaskets if the design uses them
- Protective work equipment
- Service equipment for working with the air conditioning system
3) Step-by-step assembly procedure
- Secure the vehicle against movement and prepare your work area.
- Typically, it is first necessary to professionally empty the air conditioning circuit, if there is still a charge in it.
- Access the air conditioning pipe line by removing covers or parts that prevent access.
- Disconnect the old pipe carefully so as not to damage the connecting parts or attachment points.
- Remove the old part and compare it to the new used pipe for shape, bends, ends and fittings.
- Clean the mating surfaces and check that there are no dirt, remnants of the old seal or signs of deformation.
- If gaskets are used, install them in the appropriate condition and position according to the design of the joint.
- Place the air conditioning pipe in the original route without violence and without twisting.
- Connect the individual joints and fix the pipe in the holders so that it is not under tension and does not touch places where abrasion could occur.
- Reinstall all removed covers and brackets.
- After mechanical assembly, it is typically necessary to perform a leak check and subsequent service filling of the air conditioning system using the appropriate procedure.
- After commissioning, check that the system is working stably and without signs of leakage.
-
4) Post-assembly checks and test drive/function verification
- Check that there are no signs of leakage or greasy deposits at the joints.
- Check the correct seating of the pipe in the holders and sufficient clearance from surrounding parts.
- Verify the operation of the air conditioning during normal vehicle operation.
- After a short test drive, visually check the connections and fixings again.
5) The most common assembly mistakes + how to avoid them
- Assembly without comparing the shape of the part – always compare the old and new part beforehand.
- Using a damaged seal – the sealing elements must be in good condition and properly seated.
- Tensioning of the tube after tightening – the part must fit naturally, without forced bending.
- Impurities in the joints – keep all mating surfaces clean before assembly.
- Underestimation of leak testing – always verify that the system is leak-tight and functional after installation.
Reasons why the part is damaged
- Material corrosion caused by age, humidity and operating conditions.
- Mechanical damage during disassembly, accident or contact with surrounding parts.
- Vibration and prolonged stress which can lead to cracks or material fatigue.
- Abrasion against other components due to poor guidance or loose fitting.
- Leaks in joints arising from wear of the contact surfaces or seals.
