Gaskets
Correct Standard, Correct Gasket
One of the most important criteria in gasket selection is the flange standard and pressure rating used.
Choosing the wrong standard or pressure rating can lead to sealing problems and system failures.
ASME B16.20 (ANSI)
Specifies the dimensions and tolerances of spiral-wound gaskets according to the American standard.
Widely used in high-pressure and critical industrial systems.
EN 1514-2 (DIN/EN)
Covers gasket standards according to European norms.
Has a wide range of applications in piping and industrial settings.
