High Quality 50A Silicone O-Rings

Silicone has chemical resistance to engine and transmission oil, animal and vegetable oil and grease, brake fluid, fire-resistant hydraulic fluid, diluted salt solutions, along with moderate water resistance.

Some limitations of silicone are that they are not recommended for dynamic application since it has low strength and poor abrasion resistance and high gas permeability. They are not recommended for concentrated solvents, oils, concentrated acids, diluted sodium hydroxide, hydrocarbon based fuels or aromatic mineral oil.  Also not recommended for aromatic hydrocarbons (benzene, toluene), alkalis and superheated water or steam over 250-degrees.
