Selecting the best seal for a specific application is done by optimizing several factors. These include:

  • Sealing Performance
    • Physical
    • Chemical
    • Thermal
    • Pressure/vacuum
  • Contamination
  • Economy

The following section defines many of the key terms and elastomer
properties used in seal selection.
