Hose/Line HVAC: Description and Operation
A/C Liquid Line - Description
DESCRIPTION
NOTE: LHD model shown. RHD model similar.
The A/C liquid line (1) is the refrigerant line that carries refrigerant from the A/C condenser to the A/C expansion valve. The A/C liquid line contains the
high-side service port (2), a fitting for the A/C pressure transducer (3) and uses a spring lock coupler at the condenser outlet tube connection (4). On
LHD models, the A/C liquid line is serviced only as an assembly. On RHD models, the A/C liquid line is serviced in two sections and uses a spring lock
coupler to connect the two sections together.
NOTE: Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is disconnected. Failure to replace
the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
The A/C liquid line has no serviceable parts except for the rubber O-ring seals, high-side service port valve and its protective cap and the plastic retainer
clips. 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 must be
replaced whenever the A/C liquid line is disconnected.
The A/C liquid line cannot be repaired and must be replaced if leaking or damaged.
