Installation Recommendations

Replacement of an air conditioning pipe should be performed by a qualified technician or an experienced DIYer with the correct tools. Recommended steps:

1. Recover Refrigerant: Evacuate and recover refrigerant using approved recovery equipment in accordance with local regulations.
2. Depressurize System: Ensure the system is fully depressurized before opening any fittings.
3. Access And Remove: Gain access to the faulty pipe (may require removal of engine covers, intake components or battery depending on model). Loosen and remove fittings at both ends, retaining any reusable brackets if undamaged.
4. Replace Seals: Always replace O-rings/seals at each connection with new, correct-size refrigerant-rated O-rings lubricated with the correct PAG oil type.
5. Install Pipe: Fit new pipe and torque fittings to manufacturer specification to avoid leaks or deformation.
6. Vacuum And Recharge: Evacuate system to required vacuum level, perform leak check, then recharge with the correct refrigerant type and oil quantity per vehicle specification.
7. Functional Test: Run the A/C system, check pressures and verify cooling performance and leak-free operation.

Always follow manufacturer safety procedures. Wear protective gloves and eye protection when working with refrigerant and pressurized systems.

Why This Part Most Often Fails

Air conditioning pipes commonly fail due to a combination of factors: corrosion from road salts or moisture on metal sections, mechanical damage from impacts or debris, and seal/O-ring deterioration at connection points. Vibration and thermal cycling over years can lead to fatigue at bends or joints. In vehicles exposed to harsh climates or where the pipe routing is close to moving components, the risk of chafing or puncture increases. When a leak develops, the system loses refrigerant and oil, which can quickly lead to compressor overheating and reduced cooling performance.

Practical Notes

OE Part Numbers Are Often Used By Technicians When Searching For This Component. When replacing, ensure you fit new O-rings and follow correct evacuation/recharge procedures to protect the rest of the A/C system. This pipe is commonly fitted across several Peugeot and Citroën models listed above and is a standard repair item in cooling, heating and air conditioning maintenance.

This air conditioning pipe is designed for PSA vehicles equipped with the 1.6 e-HDi engine family.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: PEUGEOT 308, 3008, 5008, RCZ; CITROËN C4, C4 II, C4 PICASSO
• Product Codes: 9684368380, 6477F4, 9831991080, 9819864880
• Additional Numbers: (T84), (T87), R134A

Function And Application

The tube is a fixed pipe/hose element of the vehicle air conditioning system that transports refrigerant between components such as the condenser, evaporator, compressor and receiver-drier/accumulator. It ensures leak-free routing under operating pressure and temperature while maintaining correct bend radii and mounting clearances specific to the vehicle models listed.

Replacement Procedure (Overview)

Replacement of the A/C tube should be performed by qualified personnel or skilled DIY mechanics with proper equipment. Typical steps:

• Recover Refrigerant: Safely evacuate and recover the R134a refrigerant using certified recovery equipment.
• Access And Remove: Remove any protective covers or brackets to access the tube. Undo fasteners and quick-connect fittings. Keep track of clamps and mounting hardware.
• Inspect And Replace Seals: Replace all O-rings and sealing elements on connections with correctly sized, lubricated O-rings (use compatible PAG oil) to ensure proper sealing.
• Install New Tube: Fit the new tube into position, secure brackets and connectors to OEM torque where specified, and ensure proper routing without kinks or contact with moving parts.
• Vacuum And Recharge: Evacuate the system to remove moisture and air, then recharge with the correct type and quantity of refrigerant (R134a) to manufacturer specifications.
• Leak Test And Function Check: Perform a pressure/leak test and verify cooling performance and system pressures during operation.

Installation Recommendations

• Always use certified refrigerant recovery and charging equipment; do not vent refrigerant to atmosphere.
• Replace O-rings at every sealing connection and lubricate them with the correct oil (PAG) to prevent leaks.
• Inspect adjacent components (compressor, condenser, receiver-drier, expansion valve) for damage or contamination; contaminated oil/detritus can damage the new tube.
• Perform a vacuum and leak test after fitting and before final charging. Verify system pressures and temperatures with diagnostic gauges.
• Follow vehicle manufacturer procedures and torque values for clamps and fittings where available.

Why This Part Most Often Fails

Common failure causes for A/C tubes include corrosion (especially in regions with road salt or high humidity), mechanical damage from road debris or incorrect routing, degradation of O-rings and seals leading to slow leaks, and stress from vibration or improper mounting. Contamination inside the A/C system (moisture, debris, or degraded oil) can accelerate wear and lead to blockages or localized corrosion. Failures typically occur after several years of service, but life expectancy depends on driving conditions and maintenance history.

Service Advice

During A/C system repairs, inspect adjoining components (compressor, condenser, evaporator, hoses and dryer/accumulator). Replace O-rings, filter-drier/desiccant and add correct type and amount of refrigerant oil as per vehicle specification. Regular visual inspections during routine servicing help catch leaks early and prevent compressor damage caused by refrigerant or oil loss.

Original air conditioning pipe (coolant line) for Peugeot and Citroën cars. This is a used OEM air conditioning duct for selected 308, 3008, 5008, RCZ, C4 and C4 Picasso models. Thanks to the precise geometry and factory quality of the material, it reliably seals and ensures the correct circulation of the coolant in the AC system. An ideal solution if you need to replace damaged or corroded wiring and maintain the original quality.

Compatibility (according to specific equipment and engine): Peugeot 308, 3008, 5008, RCZ; Citroën C4 and C4 Picasso. We recommend checking against the part number 6477G7 / 9684311080 or the VIN to ensure that the shape and connection terminals match.

Why this part often leaves: A/C pipes are exposed to moisture, road salt and vibration. Weakening of the wall at the points of attachment and subsequent leakage of coolant is typical. The manifestation is usually a loss of cooling, greasy maps near the connection, or a hissing sound. Timely replacement will prevent damage to the compressor due to running without refrigerant/oil.

Installation tips: before installation, always replace the O-rings with new ones, clean the mating surfaces and lightly coat them with suitable oil for AC. After installation, let the system be evacuated and perform a leak test, then fill with coolant and oil according to the vehicle manufacturer’s specifications. If the system has been open for a long time, consider replacing the filter-drier. Make sure that the tube is properly placed in the holders to avoid unwanted vibrations.

The advantages of the original part: precise fit without modifications, correct routing for flow and cooling, high-quality alloy and reliable terminals. In practice, this means faster assembly, better tightness and a longer service life compared to non-original alternatives.
