Air Conditioning Pipe Citroën C8 Peugeot 807 For 2.2 HDi 94 kW (4HW)
Product Description
High-quality air conditioning pipe designed for Citroën C8 and Peugeot 807 vehicles equipped with the 2.2 HDi 94 kW (engine code 4HW). This climate pipe ensures correct routing and sealing of the A/C circuit, delivering reliable refrigerant flow between components and helping maintain efficient cabin cooling. Ideal for professional workshops and experienced DIY mechanics who require a direct-fit replacement that matches original geometry and connection points.
Key Benefits
- Direct fit for Citroën C8 and Peugeot 807 2.2 HDi 94 kW (4HW) — reduces installation time.
- Correct bends and mounting points preserve system routing and prevent stress on adjacent components.
- Helps eliminate leaks that cause loss of refrigerant and loss of cooling performance.
- Suitable for mechanics and competent DIYers performing A/C repairs or system overhauls.
How It Works And Where It Fits
The pipe forms part of the vehicle’s air conditioning refrigerant circuit, conveying refrigerant between A/C components (compressor, condenser, evaporator, receiver/drier or accumulator and expansion device) depending on the vehicle layout. Proper function is essential for system pressure balance and efficient heat exchange.
Installation Overview
- Recover Refrigerant: Have the A/C system discharged and refrigerant recovered by a certified service station using approved recovery equipment before starting work.
- Access And Remove: Gain access to the routing area, remove fasteners and clamps securing the old pipe, and disconnect quick-connect fittings or threaded connections.
- Replace Seals: Replace all O-rings and sealing elements with new parts lubricated with correct A/C oil to ensure leak-free joints.
- Install New Pipe: Fit the new pipe, align mounting points, secure clamps and torque fittings to manufacturer recommendations where available.
- Vacuum And Charge: Evacuate the system to remove moisture and check for leaks, then recharge with the manufacturer-specified refrigerant and correct oil charge.
- Functional Test: Start the engine, run the A/C, and verify pressures and outlet temperature. Perform a leak check after the system reaches operating conditions.

Mounting Recommendations
- Always work with the A/C system properly evacuated and recovered by qualified personnel before disconnecting lines.
- Replace associated O-rings and sealing washers whenever lines are disturbed; lubricate seals with the correct compressor oil.
- Inspect clamps, brackets and adjacent components (condenser, dryer, compressor) for damage or corrosion and replace if necessary.
- Perform vacuum and leak tests after installation to confirm integrity before charging the system.
- Disconnect the battery if required by the vehicle manufacturer and follow all safety procedures to avoid personal injury or damage to components.
Why This Part Commonly Fails
A/C pipes typically fail due to age-related deterioration, corrosion (especially where metal components contact road salt), mechanical damage from impact or chafing, and stress from engine movement or incorrect mounting. Leaks commonly appear at connection points where O-rings harden or become contaminated with debris or incompatible lubricants. Timely inspection of hoses, clamps and fittings helps prevent progressive refrigerant loss and related compressor damage.
Replacement Advice
For best results replace the pipe as part of a full-service A/C repair when leaks or contamination are found. Always use proper recovery and charging equipment and adhere to vehicle-specific service procedures. This ensures reliable cooling performance and prolongs the service life of the system.
