Gaskets are a type of mechanical seal that fills the gap between two or more mating surfaces to prevent leakage. They are widely used in various industries, including automotive, aerospace, oil and gas, and manufacturing.
Gaskets can be made from a variety of materials, including rubber, silicone, metal, cork, paper, and felt. The choice of material depends on the application, such as temperature, pressure, and chemical compatibility.
Industrial gaskets come in a variety of materials, including metal, non-metallic, and semi-metallic. Metal gaskets are typically made from materials such as stainless steel or copper and are commonly used in high-pressure and high-temperature applications. Non-metallic gaskets are made from materials such as rubber, cork, or various synthetic fibers and are commonly used in lower-pressure applications. Semi-metallic gaskets are a combination of metal and non-metallic materials and offer the benefits of both types.
There are several types of gaskets, including:
- Spiral wound gaskets: made from a V-shaped metal strip and a soft filler material, such as graphite or PTFE.
- Ring joint gaskets: made from metal and used in high-pressure and high-temperature applications.
- Sheet gaskets: made from a flat sheet of material, such as rubber or cork, and cut to the required shape.
- O-ring gaskets: made from a circular cross-section of rubber and used in dynamic sealing applications.
