military grade gaskets

One of the best things to do when choosing a gasketing material is to pick a military specification to go along with it. There are a few reasons for this:

Reasons for Choosing a Military Specification for your Gasket:

  1. It makes it recognizable for a lot of suppliers. Any die-cutting supplier who is worth their weight will recognize the most common specifications available for their gasket materials.
  2. It nearly guarantees you the same product every time. While each manufacturer of a certain product will have slightly different properties of their materials, buying a mil spec grade gets something nearly identical everytime. This is because these specifications outline testing methods, thickness tolerances, and more.
  3. The economy of scale for these materials is pretty good. Since most gasket suppliers recognize these materials, usually a few manufacturers make this material in decent volume. For that reason, the economy of scale allows a good price point for many of these materials.
