This O-ring seals the junction between the air conditioning condenser (radiator) and associated refrigerant pipes, preventing leaks of refrigerant gas.

By maintaining a sealed system, it ensures proper cooling performance, system pressure, and efficiency of the vehicle’s climate control system.

Functions & Technical Role
•  Refrigerant sealing: Prevents gas leaks at A/C connections
•  Pressure retention: Maintains correct system pressure
•  Thermal resistance: Designed to withstand heat and cooling cycles
•  System protection: Prevents contamination and moisture ingress
•  OEM precision: Exact dimensions (approx. 23.8 x 2.4 mm) for proper fitment

Fitment / Position on car
•  Fitting position: Air conditioning system
•  Location: Between A/C condenser (radiator) and refrigerant pipes/hoses
•  System: Climate control / air conditioning refrigerant circuit

O-rings in A/C systems are exposed to pressure, refrigerant chemicals, and temperature cycles, which can cause them to harden or fail over time. A worn or damaged seal can lead to:
•  Loss of refrigerant gas
•  Reduced or no air conditioning performance
•  Increased system pressure issues
•  Costly A/C system repairs

Replacing with a genuine Porsche OE O-ring ensures proper sealing, restores cooling efficiency, and protects the entire A/C system.
