In addition to proper installation, selecting the right protective sleeve and implementing scientific maintenance are key to ensuring the long-term stable operation of automotive wiring harnesses. During the selection phase, priority should be given to the sleeve’s core performance indicators: flame retardancy must comply with vehicle safety standards; tensile strength ensures the harness is not damaged during vibration or movement; and high-temperature resistance is essential for areas such as the engine compartment. Moreover, the protective sleeve should be chosen based on the vehicle’s actual operating environment—for example, in areas prone to rodent infestation, rodent-resistant sleeves are necessary; for components exposed to long-term sunlight, UV-resistant sleeves are recommended; and in chemical or coastal environments, oil- and corrosion-resistant properties are indispensable.

For routine maintenance, it is advised that vehicle owners visually inspect the sleeve surface regularly for cracks, hardening, or deformation. Special attention should be paid to signs of Rubber aging. Follow the manufacturer’s recommended maintenance intervals for systematic inspections. For wiring harness areas frequently exposed to oil or chemical solvents, promptly cleaning surface contaminants can effectively delay sealing failure and significantly extend the service life of the protective sleeve.
