Which statement is TRUE regarding gaskets?

The statement that a gasket provides a seal between two imperfect surfaces is true and reflects a fundamental aspect of gasket functionality. Gaskets are designed to fill the gap between surfaces to ensure a proper seal, preventing the leakage of fluids or gases. This is particularly important in pipefitting, where connections may not be perfectly smooth or even, and the gasket compensates for those imperfections.

Gaskets can be made from various materials, allowing them to be used in diverse applications beyond just those involving water. Additionally, gaskets do not inherently require special tools for installation; often, they can be installed using standard tools. Therefore, the second option accurately describes the role and utility of gaskets in pipefitting and other mechanical applications.
