Coolant Hose 17128620944 For BMW F20 F21 F30 F31 F35 LCI

The water pipe connecting the auxiliary kettle of an automobile is usually composed of different kinds of materials, mainly including the following:

1. Rubber: Rubber is a common material for water pipes, which has good flexibility and wear resistance and is suitable for high-temperature and high-pressure environments. Rubber water pipes are usually used to connect engine water jacket, radiator and water pump.

2. Polyvinyl chloride (PVC): PVC is a plastic material with good corrosion resistance and wear resistance, which is suitable for general cooling systems. PVC water pipes are usually used to connect auxiliary water tanks and other cooling system components.

3. Polypropylene (PP): Polypropylene is a high-strength plastic material with excellent high-temperature resistance and chemical stability, which is suitable for high-temperature and high-pressure environments. Polypropylene water pipes are usually used to connect engine water jackets and other high-temperature parts.

4. Stainless steel: Stainless steel water pipes have good corrosion resistance and high temperature resistance, and are suitable for high temperature and high pressure environments. Stainless steel water pipes are usually used to connect radiators and other high-temperature components.

5. Aluminum alloy: Aluminum alloy water pipes have good thermal conductivity and lightweight characteristics, and are suitable for improving cooling efficiency and reducing weight. Aluminum alloy water pipes are usually used to connect radiators and other cooling system components.

Generally speaking, the water pipe connecting the auxiliary kettle of the automobile can be made of different materials, such as rubber, PVC, polypropylene, stainless steel or aluminum alloy, and the appropriate materials can be selected according to the specific use environment and requirements to ensure the normal operation and stable performance of the cooling system.
