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 disconnected.
The A/C liquid line cannot be repaired and must be replaced if leaking or damaged.
