The primary characteristics of fluororubber waterproof rings are heat resistance and solvent resistance, along with good chemical and reactive oxygen resistance, and extremely low air infiltration. Even under extreme operating conditions, it still exhibits excellent wear resistance. Fluororubber can withstand oils, gear oils, gasoline, diesel, lubricating fluids, strong oxidizers, aliphatic hydrocarbons, and aromatic hydrocarbons. However, it should not be used in the presence of esters, ethers, ketones, certain amines, and high-temperature fluorinated water and hydrogen.
