Protect your fleet's vital electrical networks from road salt, moisture, and chemical oxidation with the industry-proven Truck-Lite 97940 NYK-77 Corrosion Preventative Compound. Packaged in a professional-grade 8 oz. workbench can, this specialized non-conductive terminal grease is engineered to extend the service life and reliability of medium- and heavy-duty vehicle electrical systems.

The Truck-Lite 97940 formula forms a highly resilient hydrophobic barrier on standard open-terminal connections, preventing voltage leaks and systemic circuit failures. Ideal for routine shop service and electrical retrofits, this essential shop chemical shields open metal contacts from sub-zero winter brines, heavy rain spray, and frequent high-pressure automated fleet washings.

The Truck-Lite 97940 NYK-77 compound is the factory-recommended chemical solution for:

Coating standard trailer multi-pin plugs and receptacle interiors.
Packing commercial vehicle terminal blocks and lighting junction boxes (such as the Model 50 Series 50800/50801).
Treating terminal connections on auxiliary marker lights, stop/turn/tail lamps, and license plate lights lacking pre-sealed boot harnesses.
Cross-Product Family Availability: If a different volume is needed, the NYK-77 compound is also available as a 2 oz. tube (97944), a 14 oz. grease gun cartridge (97948), and a bulk 1-quart shop can (97943).
