Dry Film Lubricants from Zircon Industries (DirectChem) deliver superior graphite-based lubrication for railroad, industrial, and commercial maintenance applications. AAR-certified under M971-93, these quick-dry formulas protect metal-to-metal wear surfaces, switches, couplings, and engine components, available in aerosol and bulk formats across the USA and Canada.


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.
