Suction Line

Liquid Line - Typical:




The suction line is the refrigerant line that goes from the A/C expansion valve to the A/C compressor. The low side service port is integral to the suction line.

CAUTION: Use only O-ring seals specified for the vehicle. Failure to use correct O-ring seal will cause the refrigerant system connection to leak.

The suction line has no serviceable parts except the rubber O-ring seals, the service port valve core and it's protective cap. 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 suction line is removed and installed.

If the suction line is found to be leaking or is damaged, it must be replaced.
