Description
Air conditioning pipe for Citroën C4 and Peugeot 307 with 1.4 16V, 1.6 16V and 2.0 16V engines.
This air conditioning (A/C) refrigerant pipe is a direct-fit replacement for Citroën C4 and Peugeot 307 vehicles, referenced under part numbers 9681723480, 6460LV and 6460ZP. Designed for use by professional workshops and experienced DIY mechanics, the pipe restores the sealed A/C circuit, preventing refrigerant leaks and helping the system to reach and maintain proper cooling performance. The component is intended to match the original mounting points and routing to simplify installation and reduce labor time.
Function And Fitment
The pipe is a pressure line within the vehicle’s A/C system, routing refrigerant between major components such as the compressor, condenser and evaporator (or receiver/drier/accumulator depending on system layout). It provides a sealed passage for refrigerant and is sealed at the joints with O-rings or dedicated seals. Correct fitment is essential to avoid leaks and to ensure efficient system operation.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C4; Peugeot 307 (engines: 1.4 16V, 1.6 16V, 2.0 16V)
- Product Codes: 9681723480, 6460LV, 6460ZP
- Other Numbers: NFP
Installation Recommendations
- Perform A/C refrigerant recovery and system evacuation using certified service equipment before disconnecting the pipe. Never open the A/C system while pressurized.
- Replace all associated O-rings and sealing elements with new parts lubricated with the correct type and amount of compressor oil as specified by the vehicle manufacturer.
- Inspect mating fittings and adjacent hoses/components for corrosion, damage or contamination; clean or replace affected parts as needed to prevent future leaks.
- After fitting the new pipe, perform a vacuum test to check for leaks, then charge the system with the manufacturer-specified refrigerant and correct charge quantity.
- Recommend to check the A/C dryer/receiver and, if the compressor has failed or contamination is suspected, perform system flushing and replace the dryer/receiver to avoid recontamination.
Why The Part Most Commonly Fails
- Corrosion From Road Salt And Moisture: External corrosion at joints or along the pipe can lead to slow or sudden leaks.
- Mechanical Damage: Impact from road debris or previous accident damage can deform or puncture the line.
- Seal Deterioration: O-rings and seals harden with age, leading to leaks at connection points.
- Contamination From Failed Compressor: Metal debris from a failed compressor can accelerate wear and cause blockages or abrasion.
- Vibration And Fatigue: Long-term vibration can weaken bends or fittings, especially where clamps or supports are missing or damaged.
Signs That Replacement Is Needed
Reduced cooling performance, visible oil stains or refrigerant residue around fittings, audible hissing from the A/C circuit, or frequent pressure drops on system testing indicate a possible leak in the pipe and the need for replacement.
Practical Notes For Mechanics
Keep the reference part numbers (9681723480, 6460LV, 6460ZP) handy when ordering or searching for compatibility. Use proper A/C service tools and observe safety rules when working with pressurised refrigerant. Properly replacing seals and performing a full evacuation and recharge will greatly reduce the chance of rework.
