Dmaic Carbon individually matched material made of carbon-graphite or electro graphite with synthetic resin and antimony impregnation. The sealing effectiveness of Dmaic Carbon rings is achieved with a combination of careful design and painstaking craftsmanship in manufacturing.

Multi-part seal rings made of our materials can be used with direct contact or without contact (with a gap). Both rotating and oscillating movements are sealed with low friction using Dmaic material. Typical segment rings ends are either overlap or light-tight butt joints, and each joint is matched and marked.
