Superior Perfluoroelastomer O-rings (FFKM) | Accredited FFKM O-ring Producer
SJK is committed to developing high-performance sealing solutions for the most difficult conditions as a top manufacturer of FFKM O-rings worldwide. Our Perfluoroelastomer O-rings (FFKM) are the vital line of defense in semiconductor, chemical processing, and aerospace applications because they provide nearly universal chemical resistance and unmatched thermal stability.
FFKM Classification & Features
To choose the perfect seal for your specific application, we classify our Perfluoroelastomer O-rings into three application-driven categories:
- Standard Chemical Resistance Grade (FFKM-Chem): Fully fluorinated backbone offering near-universal chemical compatibility. Perfect for chemical pumps, valves, and mechanical seals handling aggressive solvents and acids.
- High-Temperature Thermal Grade (FFKM-Temp): Specially cured to withstand continuous service temperatures up to 350°C. Designed for oil/gas downhole tools, aircraft engines, and high-temperature reactors.
- Semiconductor High-Purity Grade (FFKM-Semi): Produced in our Class 100 cleanroom. provides ultra-low metal ion contamination, very little weight loss in fluorine/oxygen plasma, and extremely little outgassing.

Superior Production & Strict Testing Confirmation
SJK goes above and beyond typical manufacturing boundaries to deliver verified performance data and ultra-clean manufacture in order to satisfy the demanding needs of extreme
Industries: Ultra-High Temperature Continuous Test Curve at 300°C+
SJK's unique FFKM formulations are tested and proven, in contrast to conventional sealing materials that break down quickly in extremely hot conditions. The 300°C+ Ultra-High Temperature Continuous Test Curve from our lab demonstrates that, even when continuously exposed to 327°C (620°F), our Perfluoroelastomer O-rings maintain excellent sealing force, little compression set, and zero thermal deterioration. To obtain the whole thermal stability curve graphic, get in touch with our engineers.
Cleanroom Production Environment Class 100 (ISO Class 5)
Our high-purity FFKM series is produced, cleaned, and double-packaged in our cutting-edge Class 100 (ISO Class 5) Cleanroom to avoid microscopic contamination during semiconductor wafer processing. This guarantees that our O-rings are free of airborne particles, metal ions, and organic extractables.
Media Resistance Report on Harsh Chemicals and Highly Corrosive Substances
More than 1,800 chemicals can be withstood by SJK FFKM O-rings. Extreme media like as hot steam, strong acids (nitric, sulfuric), alkalis, ketones, esters, and aggressive plasma gases utilized in CVD/etching procedures are all covered in our thorough Harsh Chemical Resistance Reports.
