In a flange connection, the gasket must match both the flange’s dimensions and pressure class for the seal to function as intended. Flange gaskets rated according to DN and PN make it easier to select the correct size for standardized flanges, while IBC gaskets are installed inside the flange’s bolt circle.
At Cabseal, we supply DN/PN and IBC flange gaskets for piping systems, valves, pumps, and other process equipment, among other applications.
Dimension and pressure ratingThe Right Flange Gasket for the Connection
DN specifies the nominal size of the flange, while PN specifies the nominal pressure class. Therefore, both must be known in order to select the correct gasket. In addition to size and pressure, factors such as the medium and temperature must also be taken into account.
We manufacture flange gaskets made of EPDM and fiber. EPDM is used, for example, for water and steam, while fiber materials are available in various grades depending on the temperatures, pressures, and media the gasket is designed to handle.
