What is the first consideration when selecting a gasket?

Selecting a gasket begins with considering material compatibility because the gasket must withstand the specific conditions and materials it will be exposed to in a system. This includes factors such as temperature, pressure, and the type of fluids or gases being sealed. If the material of the gasket is not compatible with the medium, it can degrade, leading to leaks and potential failure of the system.

Understanding material compatibility helps ensure the gasket will maintain its integrity and seal effectively under operating conditions. This consideration is essential for the durability and reliability of the equipment. Once material compatibility is established, other factors, such as the outside diameter of the flange, inside diameter of the flange, and bolt circle, can be evaluated to ensure proper fit and function within the assembly.
