Abstract: The present invention relates to a click-on tap of a gasket for a stacked plate heat exchanger. The gasket comprises a main portion adapted to be positioned in a gasket groove formed in a heat transfer plate that encloses a heat exchanging area, said heat transfer plate further comprising a pattern of tops and valleys positioned at an outer edge region at the outer circumference of the gasket groove, and where the gasket comprises a click-on tap adapted to be positioned within a valley.
The present invention further relates to the method of attaching the gasket.
