Frenzelit Compressed Gasket Sheet

Style 7075 - NOVATEC 825F Engineered Graphite

NOVATEC 825F compressed gasket sheet made with 75% pure  graphite. It is easily identified by the cranberry colored "easy release" non-stick coating. This material's 45% compressibility allows for better sealing for those less than perfect flanges. This material does not cold flow when compressed with excessive torque. It likes stress and performs its best when compressed to 5000 PSI and beyond. This is an excellent steam sheet that works best in flanges.
