Question: 1 / 400

What is the primary purpose of seals and gaskets in machinery?

To enhance durability

To prevent leaks from fluids and gases

The primary purpose of seals and gaskets in machinery is to prevent leaks from fluids and gases. These components are specifically designed to create a tight barrier between surfaces, ensuring that substances that need to remain contained do not escape and that external contaminants do not enter the system. This is critical in maintaining the efficiency and performance of machinery, as leaks can lead to decreased functionality, increased wear, and potential damage to components or the environment.

While enhancing durability, reducing friction, and balancing loads are important aspects of machinery operations, they do not directly relate to the main function of seals and gaskets. Seals and gaskets focus primarily on maintaining integrity within fluid and gas systems, thereby playing a crucial role in the overall reliability of machinery.
