Field of Application
Some Fluid Media, Fittings, and Fitments are ubiquitous across many or all fields of application. Some, however, are specialized, having been developed for a specific industry. Some have been "borrowed into" a new field, such as the AN fitting being used extensively by automotive enthusiasts.
With some notable exceptions (such as iron pipe), we have decided to list media, fittings and fitments only in the field of application for which they were originally designed.
This is for the sake of keeping the index clear and orderly.
