This OE Match O-Ring Seal for Air Conditioning Systems is a precision-engineered sealing component developed to meet original Porsche specifications for fit, durability, and performance. This O-ring is used within the A/C system, specifically at the connections between the air conditioning condenser (radiator), dryer, and refrigerant lines, ensuring a secure and leak-free seal.
Despite its small size, this component plays a crucial role in maintaining the integrity of the A/C system. It prevents refrigerant gas from escaping and protects the system from air and moisture ingress, both of which can negatively affect cooling performance and system reliability.
Manufactured from high-quality, refrigerant- and temperature-resistant rubber, this O-ring is designed to withstand pressure, thermal cycling, and exposure to A/C gases and oils. It is typically required when replacing A/C components such as condensers, pipes, or dryers, and should always be renewed during system servicing.
With approximate dimensions of 23.8 x 2.4 mm, this OE Match O-ring is a direct replacement for original Porsche part numbers and ensures proper sealing performance across a wide range of models.
This O-ring creates a tight seal within the air conditioning system, preventing refrigerant leaks and ensuring efficient cooling performance.
Function
• Seals A/C condenser and refrigerant line connections
• Prevents refrigerant gas leaks
• Protects against moisture and air ingress
• Maintains system pressure and cooling efficiency
• Ensures reliable long-term sealing under heat and pressure
O-rings in A/C systems degrade over time due to exposure to refrigerant, oil, and temperature fluctuations. A worn or hardened seal can lead to refrigerant leaks, reduced cooling performance, and potential system damage.
Replacing O-rings during servicing ensures proper sealing, maintains system efficiency, and prevents costly repairs caused by refrigerant loss or contamination.
When to replace
• During A/C condenser, pipe, or dryer replacement
• Visible signs of refrigerant leakage
• O-ring appears flattened, brittle, or cracked
• Loss of A/C cooling performance
• Preventative replacement during air conditioning service
