Function
The pipe routes refrigerant between air conditioning components (compressor, condenser, evaporator and receiver/drier). It forms part of the high- and low-pressure circuits and must provide leak-free transfer at all fittings to maintain system efficiency.
Common Failure Reasons
- External Corrosion From Road Salt And Moisture Leading To Perforation.
- Mechanical Damage From Impacts Or Contact With Moving Parts.
- Seal And O-Ring Degradation Causing Leaks At Connections.
- Fatigue Or Cracking At Points Of Vibration Or Sharp Bends.
Replacement Guide
Practical replacement steps for trained technicians:
- Recover Refrigerant Using Certified Recovery Equipment And Comply With Regulations.
- Depressurize The System Completely Before Disassembly.
- Remove Retaining Clips And Brackets, Then Disconnect The Pipe From Fittings.
- Replace All O-Rings And Seals With Correct Sizes Lubricated With Appropriate Refrigerant Oil.
- Install The New Pipe Assembly, Secure Clamps And Torque Fasteners To Manufacturer Specifications.
- Evacuate The System With A Vacuum Pump, Perform Leak And Pressure Tests, Then Recharge With Manufacturer-Specified Refrigerant And Oil.
Installation Recommendations
Always Use New O-Rings And Lubricate Them With The Correct Refrigerant Oil Before Assembly. Inspect Adjacent Components Such As Hoses, Receiver/Drier And Compressor; Replace The Receiver/Drier If The System Was Opened To Atmosphere. Perform A Vacuum And Leak Test After Installation. Use Appropriate Personal Protective Equipment And Certified A/C Service Tools.
Why The Part Fails Most Often
The most frequent causes are corrosion from environmental exposure and mechanical damage. Degraded seals at connection points accelerate leaks. Regular inspection of A/C lines during service helps detect issues before large refrigerant loss or system contamination occurs.
Notes For Mechanics And DIYers
Identify The Correct Part Quickly By Using The OE Numbers Provided. This Is A Genuine Used Component For PSA Vehicles; When Replacing A/C Lines, Ensure Proper Evacuation And Recharge Procedures Are Followed To Protect The System And Ensure Reliable Operation.
