Function And Symptoms
The pipe is part of the vehicle’s air conditioning refrigerant circuit and carries high- or low-pressure refrigerant between components (compressor, condenser, evaporator, dryer/accumulator). When the pipe leaks or becomes blocked, symptoms include loss of cooling, hissing from under the bonnet, oil traces around connections, or visible damage to the pipe. Leaks reduce system performance and can lead to compressor damage if left unaddressed.
Replacement Procedure
Replacement should be performed by a qualified technician or an experienced DIY mechanic with the correct tools. Typical steps:
- Safely recover and store refrigerant with an approved recovery machine (legal requirement in many jurisdictions).
- Depressurize the system and remove components obstructing access to the pipe (if required).
- Disconnect fittings and remove the damaged pipe. Inspect mating surfaces and connectors for corrosion or damage.
- Replace sealing O-rings with new O-rings of the correct size and material, lubricated with the manufacturer-specified refrigerant oil.
- Install the replacement pipe, torque fittings to manufacturer recommendations, and secure clamps.
- Evacuate the system with a vacuum pump to remove air and moisture, perform a leak test, then charge the system with the correct refrigerant and oil volume according to vehicle specifications.
- Verify operation, check for leaks, and confirm proper cooling performance.
Installation Recommendation
Always use correct sealing parts (O-rings) and the manufacturer-specified refrigerant oil when assembling A/C connections. After installation perform a vacuum and leak test before charging the system. Use personal protective equipment and follow environmental and safety regulations for refrigerant handling. If you are not equipped with recovery/vacuum/charging tools, have the final evacuation, leak test and charging performed by an AC-certified workshop.
Why The Part Most Often Fails
Common failure causes include age-related degradation of O-rings and seals, corrosion of metal lines (especially in regions with road salt), mechanical damage from impacts or chafing, and stress at connection points from vibration. Contamination or incorrect oil/refrigerant use in the system can accelerate wear and cause premature leaks.
Compatibility And Search Tips
Customers often search using product numbers such as 9650200980, 9656859180 or manufacturer cross-references 6460LZ / 6460XP / 6477D4. Verify fitment against vehicle model and engine code listed in the Technical Information section to ensure compatibility.
Note
This listing describes a used component. Inspect the part visually upon receipt and replace any wearable seals during installation to ensure a durable repair.
