What is the first step when cutting a gasket?

The first step when cutting a gasket involves ensuring that the proper material is selected. Choosing the right material is critical because it affects the gasket's performance, durability, and compatibility with the substances it will be exposed to within a joint. Different applications may require specific materials that can withstand varying temperatures, pressures, and chemical exposures. For example, materials like rubber, PTFE, or cork might be used based on the requirements of the piping systems involved.

Once the appropriate material is chosen, subsequent steps like laying out the bolt circle and the outside diameter can proceed effectively, as these actions depend heavily on the characteristics of the selected material to ensure a proper fit and function.
