Ret ring with concentric serrations made of various types of metal. Serration peaks gasket was used when bolting force is not sufficient to seal a flat gasket, because it contacts flange face only at serration peaks. Commonly used on valve bannets and flanges attached to equipment. 3 types of cross section as per right table are available.

Serration peaks gasket Festures:
(1) Serration peaks gasket is suitable for high temperature and high pressure application.
(2) High corrosion resistance.
(3) Constant and teliable sealing.
