Description
Air Conditioning Pipe PEUGEOT 308 3008 5008 RCZ CITROËN C4 C4 PICASSO. Slightly damaged but fully sealing and functional.
Product Overview
This air conditioning (AC) pipe is a direct-fit climate line for a range of Peugeot and Citroën models. It is commonly searched by OE numbers and alternative codes, so customers often find this part by entering the product code into search engines or parts catalogs. The pipe carries refrigerant under pressure between system components and is essential for a leak-free, efficient HVAC system.

- Peugeot 5008 (I)
- Peugeot RCZ
- Citroën C4
- Citroën C4 Picasso
Function And Typical Failure Modes
Function: The climate pipe transports refrigerant between the compressor, condenser, dryer/receiver and evaporator. It must remain intact and correctly sealed at the fittings to maintain system pressure and cooling performance.
Why It Fails: Failures are most often caused by mechanical damage (impact from road debris), chafing against other components, corrosion at exposed metal sections or mating points, and deteriorated O-rings/seals at the connectors. Small deformations can occur after minor impacts; if the pipe remains structurally intact and fittings seal properly, it can still be serviceable.
Replacement Procedure
High-level Steps for Replacement (for professional mechanics or experienced DIYers):
- Recover Refrigerant: Recover refrigerant with a certified recovery station in accordance with local regulations.
- Access: Remove any obstructing panels or components to reach the affected pipe and its fittings.
- Disconnect: Carefully loosen the pipe fittings and remove the line. Note orientation and routing for correct reinstallation.
- Replace Seals: Install new O-rings/seals lubricated with the correct compressor oil (PAG or manufacturer-specified) at each connection.
- Install Pipe: Fit the new or repaired pipe, secure clamps and brackets, and tighten fittings to the manufacturer’s torque specifications.
- Evacuate And Recharge: Evacuate the system to remove moisture and air, then recharge with the correct refrigerant charge and oil amount per manufacturer data.
- Leak Test And Function Check: Perform a pressure/leak test and verify cooling performance at operating conditions.
Installation Recommendations
- Always Replace O-Rings: Replace all O-rings and seals when reconnecting AC lines—old seals commonly cause new leaks.
- Use Correct Lubricant: Use manufacturer-recommended compressor oil and compatible lubricants for O-rings.
- Follow Torque Specs: Tighten fittings to the manufacturer’s torque values to avoid overtightening or insufficient clamping.
- Inspect Mounting Points: Check brackets, clips and surrounding hoses for wear or rubbing that could damage the new pipe.
- Professional Service Recommended for Recovery/Recharge: Refrigerant recovery and charging should be performed with proper equipment and in compliance with legal requirements.

Why This Part Is Often Searched By Number
AC pipes are commonly identified by their OE or supplier numbers. Searching by product code such as 9684368380 or 6477F4 helps find the exact-fit part for specific vehicle variants and model years, improving chances of correct compatibility.
Advice For Buyers
Intended Audience: Suitable for professional workshops and experienced DIY mechanics who can perform refrigerant recovery and system servicing. If the pipe shows only light deformation but seals correctly, it can remain a reliable service part—ensure careful leak testing after installation.
