Direct-fit air conditioning pipe designed for Peugeot 207 and Citroën C3 Picasso models. This replacement AC pipe matches OE fitment and part number cross-references to ensure reliable refrigerant flow and leak-free connections. Ideal for professional workshops and DIY mechanics searching by part number (9671596080, 9800886980, 6477J1, 9655448980, 647705). Installing a correct-fit pipe restores system pressure integrity, reduces the risk of compressor damage, and helps maintain cabin cooling performance.

Technical Information

• Other Numbers: 9655448980; 647705

Function And Application

The AC pipe routes refrigerant between components of the air conditioning system (for example between the condenser, evaporator, dryer/receiver or compressor). It is a pressure-containing line that must maintain a tight seal under varying temperatures and vibrations to keep the system charged and efficient.

Why This Part Fails

Common causes of failure include corrosion from road salt and moisture, mechanical damage from road debris or chafing, and degradation of seals and O-rings over time. Failures typically appear as refrigerant leaks at joints or along the line, which lead to reduced cooling performance and can cause the compressor to run dry and fail if not addressed.

Installation Recommendations

For safe and correct replacement follow these guidelines:

• Recover refrigerant using appropriate certified AC service equipment before removal — do not vent refrigerant to atmosphere.
• Inspect mating surfaces and replace all O-rings and seals with new, correctly sized components lubricated with manufacturer-recommended oil.
• Ensure fittings and clamps are torque-tight according to manufacturer specifications and that hoses are routed without kinks or contact points that could cause chafing.
• After installation, evacuate the system and perform a vacuum test to verify leak-free integrity, then recharge with the correct refrigerant type and specified lubricant quantity per manufacturer documentation.
• Perform a system performance check (pressure and temperature) and verify compressor operation and cabin cooling efficiency.

Notes For Mechanics And DIY Enthusiasts

This part is commonly searched by part number, so include the referenced numbers when ordering to ensure correct selection. While replacement is straightforward for experienced technicians, refrigerant handling and system evacuation/recharge require certified recovery equipment and competence. If you are not equipped to recover and recharge refrigerant, have the system serviced at a workshop with appropriate AC service tools.

This air conditioning pipe is designed for use in Peugeot 207 and Citroën C3 Picasso vehicles. It is a direct-fit refrigerant line commonly used in the vehicle climate system to transfer refrigerant between A/C components. Suitable for professional workshops and competent DIY mechanics who service air conditioning systems, the part is often searched for by OEM numbers — making it easy to find when ordering or replacing the worn component.

Overview

The A/C pipe (climate pipe) routes refrigerant under pressure between key components of the air conditioning circuit. Depending on the vehicle configuration, it may connect the compressor, condenser, dryer/receiver or evaporator. Construction typically combines rigid metal tubing with molded rubber connections and sealing O-rings to guarantee tight joints and flexibility where needed.

How It Works And When To Replace

The pipe carries high- and low-pressure refrigerant within the A/C system. It should be replaced if there are visible leaks, corrosion, dents, crushed sections or damaged connection ends. Loss of cooling performance, hissing sounds or oil traces at joints are common indicators of a failing refrigerant line. Replacement intervals vary with use and environment; pipes in coastal or salted-road areas may fail earlier due to corrosion, while mechanically damaged pipes fail immediately after impact.

Installation Recommendations

• Recover Refrigerant Safely: Before removal, recover refrigerant with approved A/C service equipment. Handling refrigerant without proper machinery is illegal and dangerous.
• Inspect And Replace Seals: Always replace O-rings and seals at each connection. Lubricate new O-rings with the correct compressor oil (PAG or manufacturer specified) to ensure sealing and prevent leaks.
• Clean Connections: Remove debris and check mating surfaces for damage. Bent or crushed pipe sections must be replaced to avoid future leaks.
• Pressure Test And Evacuate: After fitting the new pipe, perform a vacuum and leak test using professional equipment, then recharge the system with the correct refrigerant type and charge quantity per manufacturer specifications.
• Safety And Tools: Use personal protective equipment and follow workshop safety rules. Tighten fittings to specified torque values and avoid twisting rubber sections during assembly.

Why This Part Commonly Fails

Typical causes of failure include corrosion (especially from road salt or moisture), mechanical damage from road debris, vibration fatigue at clamp points, and seal ageing leading to O-ring failure. Improper installation or reuse of old seals can also cause premature leaks. Addressing mounting points and replacing seals during service reduces the risk of repeat failures.
