Hose/Line HVAC: Description and Operation
A/C Discharge Line
DESCRIPTION
NOTE: A/C discharge line for gasoline engine shown in illustration. A/C discharge line for diesel engine similar.
The A/C discharge line (1) is the refrigerant line that carries refrigerant from the A/C compressor to the A/C condenser and includes the high side service
port (2) and a fitting (3) for the A/C pressure transducer (4).
NOTE: 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 for the metal gaskets (5) and rubber O-ring seals (6) and the high side service port valve core.
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.
