What is the main purpose of a gasket in piping systems?

The primary purpose of a gasket in piping systems is to seal joints effectively. Gaskets are used to fill the space between two or more mating surfaces to prevent leakage of fluids or gases. This sealing capability is critical in maintaining the integrity of the piping system under various pressures and temperatures.

By providing a tight seal, gaskets help to prevent any unwanted leakage that could lead to safety hazards, environmental issues, or loss of efficiency within the system. The material and design of the gasket are chosen based on the specific requirements of the system, including the type of fluid being transported and the operating conditions, ensuring that the seal remains reliable over time.

While gaskets may indirectly support pipe structures by creating a secure connection between components, their primary function is to ensure that joints are leak-proof, thereby protecting the system's overall functionality.
