A method and apparatus is provided whereby a fluid-tight seal is at least substantially assured between registered passage ends opening through mating surfaces of removably secured together components having a gasket sheet disposed therebetween provided with openings communicating the aforementioned registered passage ends. The method includes staking at least one of the mating surfaces with an elongated rod-like staking tool equipped with a first impact tool engaging end and a second work engaging end defining a circular ridge extending thereabout beveled both internally and externally to provide a resonably sharp circular apex edge, the circular apex edge being at least slight larger in diameter than the diameter of the corresponding passage end and with the staking operation forming a circular groove in the corresponding mating surface as well as circular ridges in the corresponding mating surface immediately inwardly of and outwardly of the circular groove formed in the corresponding mating surface by the staking operation.
