Graphite Mechanical Seals, also known as graphite gaskets, are thin yet robust seals designed to prevent leakage in joints. They are typically employed in applications that involve high heat and/or pressure. The longevity of these seals, coupled with their ability to create a reliable and effective seal in applications with high pressure and temperature fluctuations, makes them highly desirable.

​

These seals are indispensable in environments with aggressive chemicals, such as oil refineries and petrochemical plants, or where there are high temperatures, such as steam boilers. Their resilience and adaptability make them a preferred choice in these challenging conditions.

​

Graphite Mechanical Seals are the epitome of ideal seal parts, demonstrating dimensional stability under wide temperature variations. They are self-lapping, flexible enough to conform to the mating face, and exhibit high hardness. Their self-lubricating nature and resistance to wear further enhance their effectiveness.

​

One of the unique features of these seals is that they can be lubricated by almost any fluid. This means that the media being sealed will contribute additional lubrication, enhancing the seal's effectiveness and longevity. They are impervious and resistant to most chemicals, making them suitable for a wide range of applications.

​

Typically, Graphite Mechanical Seals are used as V-rings, O-rings, or wedges. Their versatility and adaptability make them an excellent choice for a variety of sealing applications. In conclusion, Graphite Mechanical Seals, with their unique properties and wide range of applications, play a crucial role in ensuring the efficiency and reliability of various industrial processes. Their contribution to maintaining the integrity of systems under extreme conditions is invaluable.

Products associated with Graphite Mechanical Seals. 

1.    Engine Shaft Seals: These seals are used in aerospace applications. They retain lubricants and prevent foreign particles from entering sealed cavities, which could damage machinery and lead to premature failure.
2.    Auxiliary Pumps: These are electrically controlled motors primarily used for circulating water by way of a bypass hose from the main coolant lines to a heater core.
3.    Contacting and Non-Contacting Compressor Seals: These seals are generally non-contacting, dry-running face seals, mainly used in high-speed applications. Compressors in a natural gas transfer and distribution network are a common example where these seals are routinely used.
4.    Carbon Seal Faces: They provide lubrication to seal faces, control pressure and temperature in the seal chamber and seal, flush the seal of contamination and/or residue buildup, and prevent system process fluid from leaking into the atmosphere.
5.    Segmented Seals: They are designed to prevent substances from leaking and are typically installed at the interface between a rotating and stationary component.
6.    Carbon Seals for Petrochemical Applications: They are chemically inert, oxidation-resistant and self-lubricating, making them ideal for use in environments with aggressive chemicals.
7.    Carbon Seals for Cryogenic Applications: They provide a mechanical containment mechanism for materials held at cryogenic temperatures, such as cryogenic fluids.
8.    Carbon Seals for Chemical Applications: They are chemically inert and self-lubricating, making them ideal for use in environments with a wide range of chemicals.
9.    Mechanical Seal Faces: These are an ideal material for use as a sliding face within a mechanical seal configuration. They operate successfully against counter faces in materials such as Silicon Carbide, Tungsten Carbide, and other ceramics. Mechanical Seal Faces are very hard materials and extremely resistant to wear. They are lubricated by most fluids so that the medium being sealed can serve as the seal lubricant. They are used in automotive applications, aerospace, compressor seals, petrochemical, cryogenic, chemical, and general industrial applications.
