AC hoses for automobiles are classified as rugged due to the materials used and the manner of production. These hoses, with the aid of synthetic fabric and metal braid reinforcements, are capable of withstanding severe cracking, leakage, or abrasion in the presence of high-pressure refrigerant flow and temperature differentials, thus ensuring long-life reliability. The durability expected of these components is very important for an automobile as it aids in long-term efficient vehicle cooling
