GRAFOIL

Grafoil flexible graphite is a superior performing packing and gasket material. It is the first fluid sealing material made exclusively from natural graphite flake. As a result, its resistance to corrosion, aggressive chemicals, heat and fire...make it a critical sealing solution for a variety of applicatons. Its high degree of chemical compatibility makes Grafoil inert to most chemicals and gases. It provides an excellent seal even after continuous exposure to the elements.

At Seal & Design, Inc. these materials are available in sheets, standard flange gaskets, or can be cut to any custom shape to fit virtually any application. Please contact one of our Sales Engineers, to discuss your specific application and intended purposes.
