What this part does
The A/C Line is a rigid or flexible conduit responsible for transporting pressurized refrigerant between the compressor, condenser, expansion valve, and evaporator. It routes through the engine bay and is constructed from specialized rubber and aluminum to withstand extreme temperature fluctuations and high system pressures. When this pipe develops a leak, suffers a crimp, or has degraded internal seals, the system loses its refrigerant charge. This results in the climate control blowing warm air and can lead to internal compressor damage if the system is operated while empty.

Before you order
Air conditioning routing varies heavily based on the specific climate control packages installed in the vehicle from the factory. Match the physical shape and connection points of your original A/C Line to the photos, and verify the OEM part number on your original tag. Always use brand new O-rings or sealing washers at both ends during installation to prevent slow refrigerant leaks, and ensure the system is properly vacuum-tested and recharged by a qualified technician.
