Installation Recommendation
Recover refrigerant using certified recovery equipment before starting work. Replace all O-rings and seals with new, correctly sized parts lubricated with the appropriate PAG oil. After fitting the pipes, evacuate the system with a vacuum pump to remove moisture and check for leaks using a leak detector or appropriate method. Recharge the system with the correct type and quantity of refrigerant (R134a) and the specified compressor oil according to manufacturer data. Tighten fittings to the recommended torque and secure routing to avoid chafing.
How To Replace
1) Safely recover refrigerant from the A/C system.
2) Unbolt and detach the damaged pipe sections; keep track of clamps and brackets.
3) Fit the new pipes, install new O-rings and apply correct lubricant.
4) Reassemble connections, evacuate the system, perform a leak test and then recharge to the specified refrigerant charge.
5) Run the system and verify pressure and cooling performance.
Why The Part Fails Most Often
AC pipes typically fail due to corrosion (especially at joints), mechanical damage from road debris or improper previous repairs, degraded O-rings and seals, or loss of clamping/support that causes vibration and chafing. Contamination in the system and age-related material fatigue also contribute to leaks.
Practical Tips
– Always replace O-rings when opening the system.
– Use OEM-equivalent parts and correct refrigerant oil to prevent premature leaks.
– Inspect adjacent components (compressor, condenser, hoses, dryer/accumulator) for damage when replacing pipes.
– If you are not equipped to recover and recharge refrigerant, have the refrigerant service performed by a certified workshop.
Compatibility
Fits Citroën C4 and Peugeot 307 models that use R134a air conditioning systems. Confirm fitment by matching the product codes 9658201280 or 647741 with the vehicle parts list.
