FKM (Fluorocarbon) O-rings are made from a synthetic rubber compound primarily consisting of vinylidene fluoride (VDF) and hexafluoropropylene (HFP). These seals are known for their excellent resistance to high temperatures, chemicals, oils, and fuels. FKM square-profile rings provide superior mechanical strength, excellent resistance to aging, and high resistance to aggressive media, making them ideal for high-performance applications across automotive, industrial, and aerospace sectors.

FKM Recommended Uses

Seals and gaskets, chemical processing, automotive fuel systems, hydraulic systems, aerospace applications, high-temperature applications, oil and gas industry, and extreme environment applications.

FKM Not Recommended

Ketones, esters, amines, low molecular weight acids, and some high-temperature steam systems.

FKM Limitations

Not suitable for low-temperature environments.
Limited performance in swelling from contact with certain fuels and solvents.
Not recommended for applications involving polar solvents.
Not ideal for applications that involve high shear or abrasion conditions.

FKM Usable Temperature Range

-20 to 450°F (-29 to 232°C)

FKM Also Known As

FKM, Viton®, Fluorel®, Fluroelastomer, Fluorocarbon Elastomer.
