Connection and selection
Matching assembly
Select the flange set for the exact fitting and nominal size. Confirm the required components as a complete assembly.
Flange interface
Match the flange DN and drilling to the mating component. Select the gasket and fasteners for the specified assembly.
Size and installation
Check the product-specific drawing for the required lengths and clearances. Confirm current pressure applicability and available sizes for the project.
Flange interface dimensions
EN 1092-2 flange mating dimensions for the catalogue DN and drilling groups below. PCD means bolt-circle diameter. Select the required drilling group; it does not establish the assembled product working pressure. Confirm the supplied configuration, thickness and current product drawing with AQUAFITTING before ordering.
