A heat exchanger plate has an elongated peripheral groove spaced inwardly from the edge of the plate. Openings are provided in the outer side wall of the groove. A gasket has an elongated main body portion seated in the groove with integral tabs projecting through the openings. The tabs may be long enough to be grasped from the underside of the plate and pulled through the openings to fully seat the main body portion of the gasket in the groove. The tabs may also have shoulders engaged with an edge of the openings to retain the tabs in the installed position. Tabs are also disclosed which have a button on the outer end which will snap into the opening under downward pressure. As an alternative to gasket tabs, recesses may be formed in the main body portion of the gasket to fit under tabs on the outer side wall of the plate groove.
