What is the difference between sealing and gasket?

Sealing and gasket are related terms often used in the context of preventing leaks or maintaining airtight and watertight seals in various applications. However, they refer to slightly different concepts:

1. Sealing:

  - Sealing is a broad concept that encompasses the entire process of closing or blocking off an opening or gap to prevent the passage of fluids (liquids or gases) or other materials. It can involve various methods and materials to achieve a secure closure.

2. Gasket:

  - A gasket is a specific type of sealing device. It is a mechanical seal that is used to create a barrier between two mating surfaces, such as two parts of a machine or a pipe joint. Gaskets are typically made of flexible materials, often rubber, cork, or various types of gasket paper, and are placed between the surfaces to fill irregularities and create a tight seal.

In summary, sealing is the broader concept of preventing the passage of materials through an opening or gap, while a gasket is a specific type of sealing component used to create a barrier between two surfaces, ensuring they are sealed and leak-free. Gaskets are commonly used in automotive engines, plumbing systems, machinery, and many other applications to maintain a tight seal and prevent leaks.
