Isolast K-Fab flange seal
The unique retained seal feature of the Isolast® K-Fab™ flange seal, which eases fitment of the seal into NW/KF/ISO flanges, contributes to significantly less unexpected downtime and lower cost of ownership.

Specially formulated perfluorelastomer

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 seal’s thermal properties, eliminating thermal expansion and groove overfill.

Features and benefits of Isolast® K-Fab™ flange seal 

  • High temperature resistance for use up to +325 °C / +617 °F (depending on material selection) 
  • Resistant to both extreme temperatures and the complex chemistries found in critical Sub fab environments 
  • Custom seal geometry with significantly less rubber eliminates overfill and extrusion from thermal expansion
  • Optimal seal design increases performance, especially with varying pressure or vacuum conditions for increased service life and overall lower cost of ownership
  • Seal geometry can withstand misalignment of the flange when compared with an O-Ring
  • Suitable for vacuum and overpressure conditions
  • Ideal solution wherever the chemical and thermal resistance of an O-Ring vacuum fitting solution is no longer sufficient
  • Retention mechanism offers easier handling and assembly
  • Easy to retrofit into KF, ISO, NW flange fittings as an O-Ring replacement
