Function and Typical Application
The pipe carries refrigerant between components of the air conditioning circuit. It links fixed metal lines and hoses, routing high‑ or low‑pressure refrigerant as part of the evaporator/condenser/accumulator circuit depending on the vehicle layout. Proper function is essential for correct system pressure, cooling performance and preventing refrigerant loss.
How Replacement Is Typically Done
Replacement should be carried out by a trained technician or a competent DIY mechanic with the correct equipment. Typical procedure:
- Safely recover refrigerant using an approved A/C recovery unit.
- Remove any obstructing trim or components to access the pipe and its fittings.
- Disconnect hose clamps and fittings; inspect mating surfaces and replace O‑rings/seals.
- Fit the new pipe, secure clamps and brackets to original positions.
- Vacuum the system to the required specification, perform a leak test and recharge with the correct refrigerant and oil type.
- Run the system and check pressures and cooling performance.
Typical workshop time: approximately 1–2 hours depending on access and model variant.
Installation Recommendations
- Always recover refrigerant before disconnecting any A/C component. Do not vent refrigerant to atmosphere.
- Replace O‑rings and seals at every service; lubricate new O‑rings with the correct refrigerant oil compatible with the refrigerant used on the vehicle.
- Use an A/C service station to evacuate, leak test and recharge the system to manufacturer specifications. These vehicles typically use R134a refrigerant; confirm the correct refrigerant for the specific vehicle variant.
- Inspect surrounding components (compressor, condenser, dryer/accumulator, hoses) and replace any worn or corroded parts to avoid repeat failures.
- Follow manufacturer torque and mounting recommendations for clamps and fasteners where available.
Why This Part Fails Most Often
- Corrosion and electrochemical degradation of metal lines, especially in regions using road salt.
- Aging and hardening of rubber seals and O‑rings leading to leaks at connection points.
- Mechanical damage from road debris or improper previous repairs.
- Vibration and movement where brackets or clips are missing, allowing chafing against other components.
Why Choose This Part
Direct-fit compatibility with common PSA part numbers and OE-style connections make this pipe a practical replacement for restoring A/C performance. Suitable for professional repair shops and experienced DIYers who maintain Citroën and Peugeot vehicles with the 1.6 HDi engine.
