Carbon-graphite is a self-lubricating material, and is a versatile seal face material used with mating rings of harder materials such as silicon carbide, alumina, or tungsten carbide. ZLSEAL carbon, has superior wear characteristics and broad chemical resistance. For severe corrodent including hydrofluoric and nitric acids, special carbon grades are available.
