Automotive rubber hoses can be categorized into several types based on their operating system and the medium they transport. The most common are cooling system hoses, primarily used to connect the engine and radiator, delivering coolant. These hoses require resistance to high temperatures and pressure changes.
Fuel hoses are used to transport gasoline or diesel fuel, demanding high oil resistance and sealing performance, as well as impermeability to prevent fuel evaporation. Vacuum hoses are mainly used in engine intake or control systems, requiring excellent airtightness and resistance to negative pressure.
Furthermore, brake hoses represent the highest safety level, typically employing a multi-layered design to prevent expansion and rupture under high pressure. Different types of hoses differ significantly in structure, materials, and manufacturing processes; therefore, selection must be based on the specific application.
