Function
The air-conditioning pipe carries refrigerant between components of the HVAC system (compressor, condenser, dryer/receiver, evaporator). It provides a sealed, pressure-resistant pathway that preserves refrigerant charge and allows correct heat exchange for efficient cabin cooling.
Replacement Procedure
Replacement should be performed by a qualified technician or an experienced DIYer with appropriate tools. Basic steps:
- Recover refrigerant from the system using certified recovery equipment in accordance with local regulations.
- Disconnect electrical power (battery) before starting work.
- Loosen and remove clamps or fittings securing the pipe, taking care to note routing and bracket positions.
- Inspect mating ports and replace O-rings/seals with new, correctly sized parts lubricated with the recommended PAG oil.
- Install the new pipe, secure brackets and fittings to manufacturer torque values, then evacuate and recharge the system to the vehicle manufacturer’s specifications.
Installation Recommendations
- Always Replace O-Rings And Seals: Use new O-rings sized to the original fittings and lubricate with the specified refrigerant oil.
- Follow Safety And Environmental Rules: Recover and recharge refrigerant only with certified equipment and personnel.
- Inspect Adjacent Components: Check compressor, condenser, dryer, and service ports for damage or contamination before recharging.
- Observe Manufacturer Procedures: Disconnect battery before work to avoid electrical damage and follow vehicle manufacturer guidance when removing panels or brackets.
Most Common Failure Reasons
Air-conditioning pipes typically fail due to corrosion (especially in regions using road salt), mechanical damage from impacts or rubbing, deterioration of sealing O-rings, and fatigue at flare or crimp joints. Leaks often present as loss of cooling performance or visible oil traces at connection points.
Why Choose This Part
Using the correct replacement pipe with OEM-referenced numbers (9681693180, 6477C9) ensures proper fitment, reliable sealing and restores correct refrigerant routing. Ideal for professional workshops and skilled DIYers who require a direct-fit solution for Citroën Berlingo III and Peugeot Partner III HVAC repairs.
