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:
- 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.
- 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.
- 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.
