Suction Line

DESCRIPTION





The A/C suction line (1) is the refrigerant line that carries refrigerant from the A/C evaporator to the A/C compressor. The A/C suction line is secured to the A/C expansion valve by a tapping block (2) and contains the low side service port (3). The tapping block portion of the A/C suction also secures the A/C liquid line (4) to the A/C expansion valve.

The A/C suction line is sealed to the A/C expansion valve and A/C compressor by use of rubber O-ring seals and metal gaskets.

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 suction line can be serviced separately from the A/C liquid line and has no replaceable parts except for the O-ring seals, gaskets and the low side service port valve core. The O-ring seals and gaskets must be replaced whenever the A/C suction line is removed.

The A/C suction line cannot be repaired and must be replaced if found to be leaking or damaged.
