Hose/Line HVAC: Description and Operation
A/C Suction Line - Description
DESCRIPTION
The A/C suction line is serviced in two sections. The upper section of the A/C suction line (1) is the refrigerant line that carries refrigerant from the A/C
evaporator to the A/C accumulator. The lower section of the A/C suction line (2) carries refrigerant from the A/C accumulator to the A/C compressor.
The upper portion of the A/C suction line is only serviced as an assembly with the A/C liquid line (5).
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 lower A/C suction line and the A/C liquid/suction line assembly has no serviceable parts except for the rubber O-ring seals (3), metal gaskets (4) and
the low 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 lower A/C suction line and/or the A/C liquid/suction line assembly is disconnected.
The lower A/C suction line and the A/C liquid/suction line assembly cannot be repaired and must be replaced leaking or damaged.
