Frequently Asked Questions

What is a dry film lubricant and how does it work?

A dry film lubricant applies a thin solid layer — in this case, graphite — onto metal surfaces using a liquid carrier that quickly evaporates. Once dry, the graphite reduces friction between moving parts without attracting dirt or migrating away from the application point. This makes it ideal for precision components like railroad switches, hinges, and threaded fasteners.
