Automotive AC hoses play a crucial role in air conditioning systems by transporting refrigerant from the compressor to the condenser, as well as delivering lubricant oil from the compressor to the evaporator. These hoses are constructed from a variety of materials such as rubber, plastic, and metal, with the specific material chosen based on the intended application and operating environment. To ensure durability, automotive AC hoses are commonly reinforced with either a steel braid or spiral for added strength and performance.
