The A/C suction line has no serviceable parts except for the O-ring and dual plane seal, low-side service port valve and protective cap. The seals used on
the connections are made from a special type of rubber not affected by R-134a refrigerant. The seals must be replaced whenever the A/C suction line is
removed and installed.
If the A/C suction line is found to be leaking or damaged, it must be replaced.
