Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Air Conditioning Pipe
- Product Codes: 9800404180
- Other Numbers: 9800404180 (common reference)
Function And Description
The air conditioning pipe carries refrigerant between key components of the A/C system (compressor, condenser, dryer/receiver and evaporator). It is engineered to withstand system pressure and temperature cycles while maintaining a sealed path to prevent refrigerant loss. The part typically consists of metal tubing and crimped hose connections with service fittings and sealing O-rings at connection points.
Installation Recommendations
- Recover Refrigerant First: Always recover the system refrigerant using certified recovery equipment before beginning work.
- Replace Seals: Fit new O-rings/seals lubricated with the correct PAG oil or lubricant specified for the vehicle refrigerant.
- Leak Test And Evacuate: After installation, perform a vacuum evacuation and leak test, then recharge with the correct type and amount of refrigerant for the vehicle.
- Safety Precautions: Wear protective eyewear and gloves. Work in a well-ventilated area and follow environmental and legal rules for refrigerant handling.
- Recommended For Professionals: While experienced DIYers can replace pipes, recovery/recharge and system diagnostics are best performed with proper service equipment.
Most Common Failure Reasons
Air conditioning pipes most often fail due to corrosion from road salt and moisture, physical damage from road debris or impact, and degradation of connection O-rings leading to refrigerant leaks. Vibrations and thermal cycling can also cause fatigue at joints and crimped connections. Loss of refrigerant or oil contamination accelerates wear and reduces cooling efficiency.
When replacing, ensure the cause of the leak or damage is addressed (for example, inspect surrounding brackets, mounting points and nearby components) to prevent repeat failures.
Buy this AC pipe (9800404180) to restore proper air conditioning performance in compatible Citroën and Peugeot vehicles. If you are a professional technician, this part is a straightforward replacement during an A/C service; for DIY repairs, follow the installation recommendations and use appropriate service tools for refrigerant handling.
