Description
Two connected air conditioning pipes for Citroën C8 and Peugeot 807 vehicles. For 2.0 HDi engines 88 kW and 100 kW.
These two linked A/C pipes are a direct-fit solution for the refrigerant circuit on Citroën C8 and Peugeot 807 models equipped with the 2.0 HDi engines (88 kW and 100 kW). They route refrigerant between system components and match original connection points to ensure proper sealing and reliable operation. Ideal for professional workshops and experienced DIY mechanics who need a replacement that follows factory routing and connections.
Function And Application
The pipes form part of the vehicle’s air conditioning refrigerant circuit, carrying high- and low-pressure refrigerant between the compressor, condenser and evaporator. Correct routing and secure connections are crucial to avoid leaks and ensure efficient cooling performance. These pipes are intended to replace worn or damaged lines that compromise system pressure and cooling capacity.

Replacement Procedure (Overview)
- Recover Refrigerant: Evacuate refrigerant using certified recovery equipment in accordance with legislation and environmental rules.
- Disassemble Affected Lines: Remove clamps and fastening points, carefully separate fittings and collect any old seals or O-rings.
- Replace Seals: Install new OEM-equivalent O-rings and seals lubricated with the correct PAG oil to ensure proper sealing.
- Fit New Pipes: Position the new pipes following factory routing, secure all brackets and fasteners to prevent chafing and vibration.
- Evacuate And Charge: Evacuate the system to the correct vacuum level, then recharge with the correct refrigerant and specified oil quantity.
- Leak And Performance Test: Perform a pressure/leak test and verify system cooling performance and compressor operation.
Installation Recommendations
- Always Recover Refrigerant First: Never open the A/C system while charged; use certified recovery equipment.
- Use New Seals: Replace O-rings and seals whenever lines are disturbed to avoid future leaks.
- Lubricate Correctly: Use the manufacturer-specified PAG oil when fitting seals and charging the system.
- Secure Routing: Ensure pipes are secured away from moving parts and heat sources to prevent abrasion and premature failure.
- Vacuum And Leak Test: Perform a full vacuum, hold test and leak detection after installation to confirm tightness before charging.
- Professional Tools Recommended: Use appropriate A/C service tools (recovery, vacuum pump, manifold gauges, leak detector) to meet safety and performance standards.
Common Failure Reasons
Air conditioning pipes typically fail due to corrosion from road salt and moisture, mechanical damage from stones or contact with other components, vibration fatigue at joints, or degraded O-rings and seals that lose elasticity with age. Heat cycling under the bonnet can also cause material hardening and cracking. Environmental exposure and age are the primary factors; pipes often show problems after many years of service, especially in regions with heavy use of de-icing salts.
Why Choose This Replacement
This replacement set restores correct routing and connection integrity to help return system pressure and cooling capacity to specification. For workshops, using parts with factory-equivalent connection geometry reduces diagnostic time and helps prevent repeat visits due to poor sealing or incorrect fitment.
Notes For Mechanics And DIYers
- Keep replacement O-rings and PAG oil on hand for a complete repair job.
- Inspect adjacent components (compressor, condenser, dryer/receiver, expansion valve) for damage or contamination when replacing pipes.
- After installation, monitor system pressures and perform a road test to confirm consistent cabin cooling under load.
