Technical FAQ

What is an Euroseal® 322 reinforced graphite gasket?

It is a flat industrial gasket made of three layers of expanded graphite and two stainless steel AISI 316L tanged inserts. It ensures excellent mechanical sealing even at high temperatures and on irregular surfaces.

What are the advantages of the Euroseal® 322 gasket?

  • Perfect adaptability to surfaces
  • High resistance to pressure (up to 120 bar)
  • Excellent performance at high temperatures (up to 450 °C)
  • Outstanding mechanical resilience
  • Easy handling during installation

Which industrial applications are ideal for Euroseal® 322?

It is recommended for flanges, heat exchangers, pressure equipment, and plants exposed to thermal cycles or critical environments such as power plants, chemical facilities, and refineries.

Which certifications does Euroseal® 322 have?

It is Fire Safe certified according to API 6FB, compliant with the German directive VDI 2440 for fugitive emissions, and meets TA-Luft requirements.

What is the difference between Euroseal® 322 and 322 DUAL?

  • 322: standard high-performance version
  • 322 DUAL: compatible with ASA 150/300 and UNI PN 16/40 flanges

Can the Euroseal® 322 gasket be used on damaged or non-flat surfaces?

Yes. Thanks to the mechanical resilience of graphite and its ability to adapt to surface irregularities, Euroseal® 322 is suitable even for scratched or pitted flanges, preventing the buckling effect.
