no it will not
This item is just a single gasket.
It is rated to approximately 230 °F.
You can use either gasket, the color does not matter, it is the same type of product. When buying a new pump, the gaskets should come with it, but if you need replacement gaskets either color would work.
I have seen manufacturer's instruction booklets that say you should use both kinds together but I have never found that to be necessary. Either one should work by itself, however, I have had more consistent results with the full-face type of gasket, without having to worry about torquing the bolts down hard, probably because of its large surface area. I have always thought that the red rubber flange gasket should be included with every set of flat-face flanges.
