Dry Graphite Film Lubricant — DGF Spray

Dry graphite film lubricant is used to reduce friction on metal-to-metal wear surfaces without wet, oily residue. Common applications include railroad switches, coupling components, autotrack chains, tie-down chalks, hinges, automotive and industrial gaskets, thread lubricants, and internal combustion engine components across railroad, industrial, and automotive settings.

The DGF Spray uses a quick-dry carrier formulation that evaporates rapidly after application, leaving behind a dry graphite film. It will not run or migrate once applied, making it ideal for precision applications on components where wet lubricants would attract contaminants or cause safety concerns.

The Dry Graphite Film Lubricant is available in aerosol cans (20 oz, sold in cases of 12) for precision and smaller-scale applications, and in bulk liquid formats including 4×1 gallon cases, 5-gallon pails, and 55-gallon drums for large-scale industrial or railroad maintenance operations.

Yes. The product carries the AAR M971-93 approval from the Association of American Railroads and has been individually approved for use by CSX, Norfolk Southern, Canadian National, Canadian Pacific, and all railroad contractors operating under these networks, making it one of the most broadly accepted dry graphite lubricants in North America.

The aerosol format (20 oz cans) offers precision spray for targeted, smaller-scale applications such as hinges, switches, or thread lubrication. Bulk formats (gallons, pails, drums) are designed for high-volume industrial and railroad maintenance operations where large quantities are applied systematically, reducing per-unit cost and operational downtime.

Yes. While the DGF Spray is AAR-certified for railroad use, it is equally effective across general industrial and commercial applications, including automotive gaskets, industrial machinery, internal combustion engine components, thread lubrication, and any metal-to-metal wear surface requiring a clean, dry, non-migrating lubricant film.
