The A/C discharge line (1) is the refrigerant line that carries refrigerant from the A/C compressor to the A/C 
condenser. 

The A/C discharge line has no serviceable parts except for the metal gaskets (2) and rubber O-ring seals (3). 
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 discharge line is removed and 
installed. 

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