Nylon tubes are commonly used materials in automotive pipelines. Their main components include PA6, PA11, and PA12. Nylon tubes have advantages such as oil resistance, low - temperature impact resistance, chemical resistance, resistance to battery acid and ozone. They have a wide operating temperature range, from -40°C to 125°C or 105°C. Moreover, they are lightweight, wear - resistant, and vibration - resistant.

Rubber hoses are also widely used in automobiles. They are mainly used for low - pressure pipes and high - pressure resistant pipes, which are respectively applied to working environments that require pressure, such as the cooling system and the brake hydraulic system. In addition, oil - resistant hoses are used in the fuel supply system.

Brake system pipelines include hydraulic brake hoses, pneumatic brake hoses, and vacuum tubes. Hydraulic brake hoses are responsible for transmitting hydraulic pressure to enable the normal operation of the braking system. Pneumatic brake hoses are commonly seen in commercial vehicles. Vacuum tubes assist in braking.
