Railroad Switch Lubricants

AAR M971-93 is a certification standard set by the Association of American Railroads that defines performance and safety requirements for lubricants used in railroad operations. Products bearing this approval have been tested and validated for use on railroad switches, coupling components, and related equipment, ensuring reliability and regulatory compliance across North American rail networks.

These lubricants are suitable for railroad switches, coupling components, autotrack equipment chains and tracks, tie-down chalks and hinges, thread lubricants, and all metal-to-metal wear surfaces. They are also effective on internal combustion engine components, automotive and industrial gaskets, and general industrial lubrication applications.

Yes. The product is available in multiple bulk formats including 4x1 gallon cases, 5-gallon pails, and 55-gallon drums for large-scale industrial and railroad maintenance operations. Aerosol format (12 x 20 oz cans per case) is also available for precision applications. Contact Zircon Industries at 800-547-4328 for pricing.

No. The dry graphite lubricant uses a quick-dry carrier formula that evaporates after application, leaving a dry graphite film that will not run or migrate. This makes it ideal for precision railroad components where contamination of surrounding areas must be avoided, and effective lubrication is achieved in a single pass.

Yes. The product is GSA Canadian Compliant and available with a bilingual French-language label for Canadian regulatory requirements. It is approved for use by both Canadian National and Canadian Pacific railroads, making it a suitable choice for railroad maintenance operations across the United States and Canada.

The lubricant can be applied via aerosol spray for targeted, precision applications on smaller components, or as a bulk liquid for large-scale industrial and railroad maintenance. The aerosol format offers ease of use in the field, while bulk formats suit high-volume operations. Both deliver effective lubrication with superior graphite content in a single application pass.
