What is the function of a gasket in the Ziegler case?

The function of a gasket in the Ziegler case is to create an airtight seal. Gaskets are crucial components used in a variety of mechanical applications, where they serve to prevent leaks by filling the space between two or more mating surfaces. In the context of the Ziegler case, ensuring an airtight seal is essential for maintaining the integrity and safety of the contents, especially if the case is designed to protect sensitive materials or equipment from external elements like moisture, dust, or contaminants.

While options such as providing a decorative finish, adding weight for balance, or enhancing aesthetic appeal might be features of certain products, they do not pertain to the functional role that gaskets play in mechanical assemblies. A gasket is fundamentally about sealing rather than aesthetics or usability related to weight. Therefore, creating an airtight seal stands out as the primary and most important function of the gasket in this context.
