FF352-75 Datasheet

Parker’s FF352-75 is a 75 Shore A white perfluoroelastomer (FFKM) compound engineered for ultra high-temperature sealing in chemically aggressive environments where purity and thermal stability are critical. 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 compound performs reliably in water and steam service, petroleum oils, and wet or dry chlorine exposure, while exhibiting minimal weight loss in high-vacuum conditions. Its white formulation supports visual inspection and use in applications where cleanliness and contamination control are important.

 

FF352-75 is commonly used in O-rings, gaskets, and custom seals for chemical processing equipment, high-temperature reactors, vacuum systems, and severe service industrial applications. It is not recommended for fluorinated refrigerants, uranium hexafluoride, molten metals, or gaseous and alkali metals. This ultra high-temperature FFKM formulation provides dependable performance where combined heat, vacuum, and aggressive chemistry challenge conventional elastomers. Canyon Components offers equivalent FFKM materials designed to match or exceed the chemical resistance, temperature capability, and vacuum performance of Parker FF352-75 for demanding sealing applications.
