The A/C discharge line (1) is the refrigerant line that carries refrigerant from the A/C compressor to the A/C condenser. The A/C discharge line contains a fitting (2) for the A/C pressure transducer (3) and is secured to the A/C compressor and the A/C condenser by use metal fittings (4).The A/C discharge line is sealed to the A/C compressor and to the A/C condenser by use of rubber O-ring seals (5) and metal gaskets (6). The O-ring seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant.Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failure to replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.The A/C discharge line has no serviceable parts except the O-ring seals and gaskets. The O-ring seals used on the connections are made from a special type of rubber not affected by R-134a refrigerant. The O-ring seals and gaskets must be replaced whenever the A/C discharge line is removed.The A/C discharge line cannot be repaired and must be replaced if found to be leaking or damaged.
