Graphite based sealing materials are great at compensating for minor imperfections on the flange sealing surface. Combining graphite with stainless steel or nickel reinforcement increases the performance. Different styles of reinforcement are available, so please consult with William Johnston and Company Limited to ensure you have the best available material for your application.
