In the gasketing of plate heat exchangers, it has long been conventional for a compressible elastomer gasket to be secured in a gasket recess by means of an adhesive. In accordance with the invention, it is proposed that a gasket should be in two parts, namely a relatively hard outer part which is secured by adhesive or otherwise to a plate, and a soft sealing part which is received in a gasket recess defined in part by the outer part and is mechanically retained by the outer part so that it can be comparatively easily installed and removed.
