Information
Air conditioning refrigerant pressure line.
This OE Match air conditioning refrigerant pressure line is a replacement A/C pipe for Porsche 9YA Cayenne 3.0L models. It is designed to match the original-style fitment and function, helping maintain correct refrigerant flow within the vehicle’s air conditioning system.
Fits:
Porsche 9YA Cayenne 3.0L petrol 2018 - 2024 (PR:DU6)
* Refrigerant R1234yf (option code: KK3)
Diagram ref no 7
The refrigerant pressure line carries air conditioning refrigerant between A/C system components under pressure. It helps the system circulate refrigerant correctly so the air conditioning can cool the cabin efficiently and operate as intended.
Functions
• Carries refrigerant through the air conditioning system
• Helps maintain correct A/C system pressure and flow
• Supports efficient cabin cooling performance
• Connects designated air conditioning system components
• Helps prevent refrigerant leaks when correctly installed
• Replaces damaged, leaking, corroded, or worn original pressure lines
• OE Match replacement for A/C system repair and service.
Why Replace This Part?
Air conditioning refrigerant pressure lines can become damaged by corrosion, vibration, impact, age, or seal failure. A leaking or damaged pressure line can cause refrigerant loss, poor cooling, A/C system pressure faults, or complete air conditioning failure. Replacing the line helps restore correct refrigerant circulation and supports reliable climate control operation.
When to Replace This Part
• The A/C pressure line is leaking refrigerant
• The pipe is corroded, cracked, bent, or physically damaged
• The air conditioning system is not cooling correctly
• Refrigerant pressure faults are present
• Oil or dye residue is visible around the A/C line or joints
• The line has been damaged during engine bay or front-end repairs
• The A/C system is being serviced, repaired, or recommissioned.
Where it fits on the car
This refrigerant pressure line fits within the air conditioning pipework system on Porsche 9YA Cayenne 3.0L models. It connects between the specified A/C system components according to the vehicle’s factory diagram and refrigerant circuit layout.
