FDA-compliant FKM (Fluorocarbon) O-rings are made from a high-performance synthetic elastomer primarily composed of vinylidene fluoride (VDF) and hexafluoropropylene (HFP). These seals are specifically formulated to meet FDA standards for use in food, beverage, and pharmaceutical applications where chemical resistance and cleanliness are essential. FKM FDA O-rings provide exceptional resistance to high temperatures, oils, fuels, and a wide range of chemicals, making them suitable for demanding sanitary processing environments.

FKM FDA Recommended Uses

Food and beverage processing, pharmaceutical equipment, chemical processing, fuel handling systems, high-temperature sealing applications, oil and gas environments, and cleanroom applications.

FKM FDA Not Recommended

Ketones, esters, amines, low molecular weight acids, and applications requiring resistance to hot water or steam for extended durations.

FKM FDA Limitations

Not suitable for continuous exposure to hot water or steam.
Limited flexibility in low-temperature environments.
Not ideal for polar solvents or strong organic acids.
May exhibit swelling with certain aggressive fuels or solvents.
