Gaskets How Are They Made and What Are Common Types

Gaskets are components that are commonplace in a variety of industries, serving to provide a tight seal between two surfaces to prevent the leakage of fluids or gasses. These components are used in everything from household appliances to industrial machinery and aircraft, a testament to their widespread importance. In this blog, we will help you better understand how gaskets are made and the different types available on the market, ensuring you can choose the right one for your specific application.

The manufacturing process of gaskets involves several steps, starting with the selection of an appropriate material. The choice of material depends on the application’s specific requirements, such as the necessary temperature resistance, chemical compatibility, and pressure tolerance for optimal operations. Common materials used in gasket manufacturing include rubber, fiber, cork, metal, and combinations of these materials.

Once the material is selected, it is cut into a desired shape and size using various basic methods. For simple shapes, manual cutting or die-cutting is sufficient enough. However, more complex shapes require advanced techniques such as laser cutting or water jet cutting, which provide greater accuracy. The cutting process is important as it ensures that the gasket will fit perfectly into the intended application, providing an effective seal.

After cutting, the gasket may undergo additional processing like coating or laminating to enhance overall properties. For instance, rubber gaskets can be coated with a thin layer of silicone to improve temperature resistance and chemical compatibility, while metallic gaskets may be laminated with a soft material like graphite to enhance their sealing capabilities. As these properties can have a major effect on overall compatibility and performance, it is important to ensure that the right lamination or coating is determined.

Rubber gaskets are among the most common types available, and they are primarily known for their flexibility and resilience. They are made from various types of rubber, including natural rubber, neoprene, and silicone. As a result of upholding reliable sealing and resistance to water, oil, and other fluids, the common applications of rubber gaskets range from automotive engines to plumbing systems.

Fiber gaskets are made from compressed fibers, which are then often combined with rubber binders. They are typically used in applications where chemical resistance and temperature stability are crucial, a result of their ability to maintain a tight seal when placed under harsh environmental conditions. Fiber gaskets can also withstand high pressures, which is beneficial for settings like chemical processing plants and oil refineries.

Cork gaskets are a variation made from natural cork material, which is harvested from the bark of cork oak trees. Cork is known for its excellent compressibility and flexibility, making it ideal for applications where it achieves a tight seal despite surface irregularities. Cork gaskets are often used in automotive and industrial applications because of their natural properties that make them resistant to oil, fuel, and other hydrocarbons.

Jacketed gaskets consist of a soft filler material encased in a metal jacket, where the jacket provides strength and stability and the filler ensures a tight seal. Jacketed gaskets are regularly relied on in high-temperature and high-pressure applications, such as steam systems and heat exchangers.

Metallic gaskets are made entirely of metal materials for the sake of withstanding the most demanding applications. They are typically used in high-pressure and high-temperature environments, such as power plants and petrochemical facilities, and they come in subtypes like spiral wound gaskets and ring joint gaskets, to offer specific sealing properties.

While various types of gaskets are available on the market, the selection of the appropriate one will depend on several factors like the nature of the fluid or gas being sealed, the operating temperature and pressure, and the compatibility with the surfaces being sealed. It is essential to consider these factors to ensure that the gasket will perform effectively and provide a reliable seal.
