Gaskets play a critical role in industrial piping systems by creating a reliable seal between two mating surfaces. Whether used in oil & gas pipelines, chemical plants, power generation units, or water treatment facilities, selecting the correct gasket size and thickness is essential for leak-free performance. One often overlooked but important factor in gasket selection is gasket weight, which directly depends on its size, thickness, and material density. This article explains gasket weight in detail, including size and thickness charts in kilograms and millimeters, along with practical calculation examples.
