Description
Air conditioning tube for PEUGEOT 308, 3008, 5008, RCZ and CITROËN C4, C4 II, C4 PICASSO
Direct-fit air conditioning tube designed for Stellantis vehicles from the Citroën and Peugeot families. This climate pipe (common references 9684368380, 6477F4, 9831991080, 9819864880) routes refrigerant within the A/C circuit and is suitable for a range of models including Peugeot 308, 3008, 5008 and RCZ as well as Citroën C4 variants and C4 Picasso. Built to OEM mounting points and connection geometries, it helps restore proper refrigerant flow and prevents leaks that cause loss of cooling performance. Ideal for professional workshops and experienced DIYers performing A/C repairs or component replacements.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: PEUGEOT 308, 3008, 5008, RCZ; CITROËN C4, C4 II, C4 PICASSO
- Product Codes: 9684368380, 6477F4, 9831991080, 9819864880
- Additional Numbers: (T84), (T87), R134A
Function And Application
The tube is a fixed pipe/hose element of the vehicle air conditioning system that transports refrigerant between components such as the condenser, evaporator, compressor and receiver-drier/accumulator. It ensures leak-free routing under operating pressure and temperature while maintaining correct bend radii and mounting clearances specific to the vehicle models listed.
Replacement Procedure (Overview)
Replacement of the A/C tube should be performed by qualified personnel or skilled DIY mechanics with proper equipment. Typical steps:
- Recover Refrigerant: Safely evacuate and recover the R134a refrigerant using certified recovery equipment.
- Access And Remove: Remove any protective covers or brackets to access the tube. Undo fasteners and quick-connect fittings. Keep track of clamps and mounting hardware.
- Inspect And Replace Seals: Replace all O-rings and sealing elements on connections with correctly sized, lubricated O-rings (use compatible PAG oil) to ensure proper sealing.
- Install New Tube: Fit the new tube into position, secure brackets and connectors to OEM torque where specified, and ensure proper routing without kinks or contact with moving parts.
- Vacuum And Recharge: Evacuate the system to remove moisture and air, then recharge with the correct type and quantity of refrigerant (R134a) to manufacturer specifications.
- Leak Test And Function Check: Perform a pressure/leak test and verify cooling performance and system pressures during operation.
Installation Recommendations
- Always use certified refrigerant recovery and charging equipment; do not vent refrigerant to atmosphere.
- Replace O-rings at every sealing connection and lubricate them with the correct oil (PAG) to prevent leaks.
- Inspect adjacent components (compressor, condenser, receiver-drier, expansion valve) for damage or contamination; contaminated oil/detritus can damage the new tube.
- Perform a vacuum and leak test after fitting and before final charging. Verify system pressures and temperatures with diagnostic gauges.
- Follow vehicle manufacturer procedures and torque values for clamps and fittings where available.
Why This Part Most Often Fails
Common failure causes for A/C tubes include corrosion (especially in regions with road salt or high humidity), mechanical damage from road debris or incorrect routing, degradation of O-rings and seals leading to slow leaks, and stress from vibration or improper mounting. Contamination inside the A/C system (moisture, debris, or degraded oil) can accelerate wear and lead to blockages or localized corrosion. Failures typically occur after several years of service, but life expectancy depends on driving conditions and maintenance history.
Notes For Buyers
Use the product codes listed above (9684368380, 6477F4, 9831991080, 9819864880) when searching for exact matches. This item is intended for vehicles using R134a refrigerant. For best results, pair replacement of the tube with inspection or replacement of the receiver-drier/accumulator and replacement of O-rings.
