One of the main accessories in the fuel sensor is the oil-resistant plastic hollow pepper ball. The oil-resistant plastic pepper ball can be a hollow structure or a plastic foamed pepper ball, but the plastic foamed pepper ball has been eliminated because of its low precision and unstable density. Now PA plastic hollow pepper ball is the mainstream in the market.

PA plastic hollow pepper ball has the advantages of high precision, good surface finish, resistance to diesel oil, gasoline and kerosene, better temperature resistance than rubber ball, low temperature of minus 40 degrees, and high temperature of 100 degrees. PA nylon hollow pepper ball has excellent toughness, no cracking, high strength, good sealing effect of oil-resistant PA nylon hollow pepper ball, which can ensure that the fuel tank does not leak, and its safety performance reaches the advanced level of similar products abroad.
