Flat metal seal gasket
DONIT TESNIT, d.o.o.

The metal eyeleted flat gaskets offer special protection against blowout for the sealing of critical or dangerous media. The sealing insert is usually made from TESNIT BA or Grafilit gasket material. The standard metal jacket is formed with an austenitic stainless steel leaf with a thickness of 0.15 - 0.2 mm U-shaped and pressed in such a way that it becomes a single body with a base seal. The good malleability grade of the austenitic stainless steel gives to the covering excellent mechanical properties and good resistance to erosion, while the well know resistance to heat and to corrosion ensures the long working life of the seal.
Advantages

-Blow out protection.
-Protection against chemical attack.
-Improved sealability due to the local higher stress under eyelet.
