The fuel tanks of fuel vehicles are equipped with sensors to monitor the remaining amount of oil in the fuel tanks. Usually, the fuel sensors in diesel vehicles are equipped with an oil-resistant plastic nylon hollow pepper ball, which is usually made of PA material, and PA nylon material has the characteristics of oil resistance, high temperature resistance and low temperature resistance.

PA nylon plastic hollow pepper ball used in fuel sensor requires a density of 0.3-0.4g/cm, high temperature resistance of 100 degrees, low temperature resistance of minus 40 degrees, and accuracy of within 0.02. A product developed by Dongguan Jiaji Plastic Ball Co., Ltd., PA nylon hollow pepper ball product is widely used in sensors of various diesel vehicles, allowing customers to call to discuss cooperation.
