Product Description

Product Description

Cooling Hose

A/C Lines are critical components of the automotive thermal management system, designed to connect the compressor, condenser, expansion valve, and evaporator, ensuring stable circulation of refrigerant between the high-pressure and low-pressure sides to achieve effective cabin cooling. These lines are typically manufactured from aluminum tubes, rubber hoses, or hybrid assemblies that combine rigid and flexible sections, offering both strength and flexibility to accommodate complex routing and vibration resistance. A/C Lines must provide excellent resistance to high and low temperatures, corrosion, and refrigerant permeation, preventing leakage and ensuring long-term system reliability. As a result, they play a vital role in enhancing air conditioning efficiency and passenger comfort.
