The condenser refrigerant lines connect the compressor to the condenser, and the condenser to the evaporator. The line from the compressor carries hot, high-pressure vapor. The exit line carries high-pressure liquid. These lines are made of aluminum tubing with rubber sections to allow engine movement.

The metal and rubber hoses that transport high-pressure refrigerant to and from the condenser.
Frequently Asked Questions
A coat of oil on an A/C line indicates a refrigerant leak. Oil escapes along with the gas, trapping dust on the line surface.
Standard patches won't hold the 200+ PSI system pressure. Replace the entire line assembly for a reliable fix.
The rubber sections absorb the torque movement of the engine, preventing the rigid aluminum lines from cracking.
