ABSTRACT:
Each plate of the heat exchanger has the usual groove for receiving a gasket. The gasket has a main body portion secured to the bottom of the groove by spots of glue at spaced points along the length of the groove. The gasket is free of attachment to the groove between the spaced points. Nubs may be molded on the outer or inner edge of the gasket at spaced points to indicate where the glue is applied. The nubs lie in lateral extensions of the groove. The spots of glue, instead of being located in the groove proper to adhere the main body portion of the gasket, may be located in the groove extensions to adhere the nubs.
