The refrigerant pressure line carries air conditioning refrigerant between A/C system components under pressure. It helps the system circulate refrigerant correctly so the air conditioning can cool the cabin efficiently and operate as intended.

Functions
•  Carries refrigerant through the air conditioning system
•  Helps maintain correct A/C system pressure and flow
•  Supports efficient cabin cooling performance
•  Connects designated air conditioning system components
•  Helps prevent refrigerant leaks when correctly installed
•  Replaces damaged, leaking, corroded, or worn original pressure lines
•  OE Match replacement for A/C system repair and service.

Why Replace This Part?
Air conditioning refrigerant pressure lines can become damaged by corrosion, vibration, impact, age, or seal failure.
