Sealing rings
Our supplier have been manufacturing graphite rings for the valve industry since the early 1970’s and deliver to customers all over the world. Rings are handcrafted by experienced personnel from graphite flakes that have been expanded through a heating process and converted into a graphite foil. The rings provide permanent elasticity and superior strength, thermal conductivity and spring-back resilience.
