FFKM O-rings

O-RINGS

Perfluoroelastomer, commonly abbreviated as FFKM, is a high-performance elastomer widely used in sealing applications across various industries. Known for its exceptional chemical resistance, FFKM is ideal for environments that require durability against aggressive chemicals, high temperatures, and harsh conditions.

With a robust, chemically stable structure, FFKM resists degradation from exposure to oils, fuels, and solvents, making it suitable for use in demanding applications. It can withstand extreme temperatures and provides excellent flexibility across a wide range of environmental conditions. FFKM is particularly favored in applications where other elastomers may fail due to harsh chemical exposure.

Primarily used in industries such as chemical processing, aerospace, and semiconductor manufacturing, FFKM O-rings offer reliable sealing solutions for extreme conditions. For optimal performance, FFKM O-rings typically do not require lubrication due to their inherent properties, but specific applications may still benefit from compatible lubricants.

Features and Specifications

Temperature Range

Standard FFKM O-ring temperature ranges typically extend from -15°F to 600°F, with some specialized formulations capable of withstanding even higher temperatures. These temperature limits are based on dry air, but actual performance may vary depending on the specific application and environmental conditions.

Durometer

Standard durometer (hardness) for FFKM O-rings typically ranges from 60 Shore A to 90 Shore A, with 75 Shore A being the most common. This range provides flexibility, allowing FFKM to be customized for specific sealing applications by balancing hardness with elasticity.

Color

FFKM O-rings are often black but can also be manufactured in various colors to meet specific application requirements.

Benefits of FFKM O-rings

FFKM O-rings provide outstanding resistance to aggressive chemicals, high temperatures, and environmental degradation, making them well-suited for demanding sealing applications in industries such as chemical processing, aerospace, and semiconductor manufacturing. Known for their durability in extreme conditions, they deliver reliable sealing performance, ensuring long-lasting seals even in challenging environments. FFKM O-rings are highly versatile, offering an excellent balance of chemical resistance, heat tolerance, and mechanical strength, making them a preferred choice for high-performance applications.
