How do I choose a gasket?

Some factors that buyers should consider as they purchase gaskets include:

  1. The amount of force the two surfaces will exude on the gasket.
  2. The degree of surface unevenness (which dictates how thick the gasket should be)
  3. The fluids and any ambient contaminants.
  4. The compressibility of the gasket material.

What is the most important factor when selecting a gasket?

Temperature The first consideration when selecting a material for your seal or gasket is temperature since it can change the characteristics of the material. Extreme heat, cold, or widely fluctuating temperatures can affect material sealing properties, maximum allowable stress, and overall performance.
