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 Size and construction custom made gaskets Gaskets are available in ANSI B 16.21, DIN2690, other Standard Forms, or as custom made gaskets.
