FFKM Rubber O-Ring

Place of Origin: China
Payment: T/T

Perfluoroelastomer (FFKM) rubber O rings exhibit exceptional resistance to extreme temperatures, with a range spanning from -10°C to +260°C. Certain specialized compounds even possess the capability to function effectively beyond the threshold of 300°C.

FFKM O rings demonstrate remarkable resilience against extreme temperatures, offering a temperature range from -10°C to +260°C. Certain specialized compounds can even withstand operation beyond 316°C. Notably, FFKM O rings exhibit unparalleled resistance to a wide array of chemicals, including inorganic acids, alkalines, ketones, esters, alcohols, fuels, and hot water. This exceptional chemical resistance renders them suitable for deployment in aggressive chemical environments, finding use in applications spanning highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceuticals, oil and gas recovery, and aerospace.

The established, enduring performance of FFKM parts translates to reduced frequency of seal replacements, repairs, and inspections, contributing to heightened process and equipment uptime, ultimately leading to enhanced productivity and yield. Moreover, FFKM O rings offer low outgassing characteristics, making them well-suited for vacuum-sealing applications.
