Coolant Hose 11537584549 B For BMW  E88 E82 E90 E91 E84

Water pipe joints can be made of aluminum or plastic materials, which have some differences in the following aspects:

1. Material characteristics: aluminum joints are usually made of aluminum alloy, which has high strength and corrosion resistance and can withstand high pressure and temperature. Plastic joints are usually made of polymer materials (such as nylon or polypropylene), which have low strength and corrosion resistance and are generally suitable for low pressure and low temperature applications.

2. Corrosion resistance: The aluminum joint has good corrosion resistance, which can resist corrosive substances in the coolant and prolong the service life. Plastic joints have poor corrosion resistance and are easily corroded by chemicals in coolant, which may lead to joint aging and leakage.

3. Sealing: Aluminum joints usually have good sealing performance, which can effectively prevent coolant leakage. The sealing performance of plastic joints is poor, which is prone to leakage problems and requires additional sealing measures.

4. Weight: Aluminum joints are relatively heavy, but they are also more durable. Plastic joints are relatively light, but they are also fragile and easily damaged by external forces.

5. Cost: Generally, the manufacturing cost of aluminum joints is higher, while the manufacturing cost of plastic joints is lower.

The choice of aluminum connector or plastic connector depends on the specific application requirements. For high pressure, high temperature and corrosive environment, aluminum joint is more suitable; For low pressure, low temperature and general environment applications, plastic joints can meet the demand and have cost advantages.
