Webinar: Isolast® K-Fab™ Seal 

K-Fab webinar_WEB
Engineered for critical Subfab applications, the Isolast® K-Fab™ flange seal from Trelleborg Sealing Solutions, gives long-term sealing and increased productivity in today’s most extreme Subfab conditions. On April 28, join Trelleborg Sealing Solutions experts to learn more about this unique solution.

The traditional sealing method for flanges has been with an O-Ring. However, as conditions within the flange become more challenging, O-Rings are subject to premature failure. The Isolast® K-Fab™ flange seal offers a solution to this.


A perfluoroelastomer (FFKM) specifically formulated for semiconductor applications forms the sealing element of the Isolast® K-Fab™ flange seal. This is resistant to both extreme temperatures and the complex chemistries found in critical Subfab environments. The elastomer element uses far less material than traditional O-Rings, improving the seals thermal properties, eliminating thermal expansion and groove overfill.
