Gasket materials are substances used to create a seal between two surfaces, preventing leaks of fluids or gases. Common materials include rubber, silicone, metal, and composite materials. Each type has unique properties, such as flexibility, temperature resistance, and chemical compatibility, making them suitable for various applications in industries like automotive, aerospace, and manufacturing. Choosing the right gasket material is crucial for ensuring the longevity and efficiency of machinery. Factors to consider include the operating temperature, pressure, and the type of fluid or gas involved. Proper selection helps maintain system integrity and reduces the risk of failures or leaks.
