Home Products Machinery Industry / Graphite Seal Rings
Graphite seal rings are sealing elements made from graphite-based materials, used to prevent leakage between two surfaces. They are prized for their ability to withstand extreme temperatures, pressures, and chemical environments, as well as their self-lubricating properties.Graphite seal rings are high-performance sealing components widely used in industrial applications that require excellent thermal resistance, chemical stability, and low friction. These rings are made from high-purity graphite or reinforced carbon-graphite materials, often impregnated with resins or metals to enhance their durability and sealing performance.
Graphite sealing ring is a component used for mechanical seals. Its high strength, low friction, high temperature and high pressure resistance and self-lubrication make it an ideal choice for dynamic and static sealing ring materials. It is made from high purity graphite or impregnated resin/metal graphite to achieve superior performance.
Graphite sealing rings are divided into static and dynamic sealing rings, with static sealing rings installed on fixed components and dynamic sealing rings installed on rotating shafts. These sealing rings are usually used in applications such as pumps, compressors, and turbines to form a sealing interface that prevents liquid or gas leakage. Therefore, it puts high requirements on the performance of sealing rings, including strength, hardness, porosity, lubrication, and heat resistance.
Self-lubrication, low friction.
High tensile strength and good thermal shock resistance.
High conductivity, low coefficient of thermal expansion.

Excellent high temperature stability.
Graphite seal rings are used in a wide variety of industries and applications, including:
Pumps and Compressors: Sealing rotating shafts to prevent leakage of fluids or gases.
Valves: Sealing valve stems and seats to prevent leakage.
Steam Turbines: Sealing high-pressure steam.
Aerospace: Sealing in engines and other critical components.
Chemical Processing: Handling corrosive chemicals and high temperatures.
Petroleum Refining: Sealing in pumps, valves, and reactors.
Nuclear Power: Sealing in critical systems.
