Parker’s FF354-65 is a low closure force, 65 Shore A white perfluoroelastomer (FFKM) compound engineered for ultra high-temperature sealing applications where reduced sealing load and broad chemical resistance are required. With a recommended service temperature range of 5°F to 608°F, it maintains sealing integrity in aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, polar solvents such as acetone, MEK, and dioxane, as well as a wide range of inorganic and organic acids. The lower durometer allows improved conformability and effective sealing at reduced clamp loads, making it well suited for delicate hardware and applications sensitive to compression force. It also performs reliably in water and steam service, petroleum oils, wet or dry chlorine exposure, and high-vacuum environments with minimal weight loss.
FF354-65 is commonly used in O-rings, gaskets, and custom seals for chemical processing equipment, high-temperature reactors, vacuum systems, and other severe service environments where both heat resistance and gentle sealing force are important. It is not recommended for fluorinated refrigerants, uranium hexafluoride, molten metals, or gaseous and alkali metals. This white FFKM formulation provides a balance of ultra high-temperature capability, chemical durability, and low sealing stress. Canyon Components offers equivalent FFKM materials designed to match the temperature performance, chemical resistance, and low closure force characteristics of Parker FF354-65.
