Gaskets are typically specified based on which parameters?

Gaskets are typically specified based on the parameters of pressure and temperature because these factors directly impact the gasket's ability to create a reliable seal under operational conditions. The pressure represents the force exerted by the contents being contained, which can vary significantly in industrial applications. High pressure requires a gasket that can withstand and maintain integrity without leaking.

Temperature is also crucial because materials can behave differently at varying temperatures. Higher temperatures can lead to material degradation or alteration in properties, affecting the gasket's performance. Therefore, understanding the maximum pressure and temperature that a gasket can handle ensures that it will be effective and safe in its application. Proper selection based on these parameters helps in preventing leaks, ensuring system efficiency, and maintaining safety standards in processes involving fluids or gases.
