Hose/Line HVAC: Description and Operation
A/C Liquid Line
DESCRIPTION
The A/C liquid line is the refrigerant line that carries refrigerant from the A/C condenser to the A/C evaporator. The A/C liquid line uses a spring-lock
type refrigerant line coupler with three O-rings to connect and seal it to the A/C evaporator.
The A/C liquid line includes the high-side service port, the fixed A/C orifice tube and a fitting for the A/C pressure transducer.
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 liquid line has no serviceable parts except for the O-ring seals, gasket, A/C pressure transducer, high-side service port valve and cap and the
secondary retaining clip. 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 liquid line is removed.
The A/C liquid line cannot be repaired and must be replaced if found to be leaking or damaged.
