A gasket assembly of a plate heat exchanger, comprising at least one gasket ( 3 ) and a package of heat exchanger plates ( 2 ) which are provided with inlet and outlet ports ( 4, 5, 6, 7 ) which constitute channels through the package and between the heat exchanger plates, whereby the heat exchanger plates are permanently joined in pairs to constitute cassettes ( 1 ), the gasket is disposed between the cassettes in a groove ( 12 ) in the heat exchanger plates and delimits in combination with the cassettes in every second space between plates a first flow passage for a first fluid, and the cassettes delimit a second flow passage for a second fluid. The gasket in the area around the ports comprises along its side facing the porthole a circumferential protruding bead ( 14 ).
