-
High-Volume Fleet Efficiency: The ideal packaging size for commercial repair bays, logistics hubs, and trailer manufacturing lines, significantly reducing servicing time per rig.
-
Thermal and Chemical Stability: Formulated to stay thick and perfectly in place within extreme temperature environments without running, thinning out, or hardening into a brittle crust.
-

Truck-Lite 97948 – NYK-77 Corrosion Preventative Compound, 14 oz. Grease Gun Cartridge
Streamline high-volume fleet maintenance and protect your commercial vehicles from electrical failures with the bulk Truck-Lite 97948 NYK-77 Corrosion Preventative Compound. Formulated into a standard 14-ounce (14 oz.) drop-in cartridge, this industry-preferred non-conductive grease is specifically designed to fit standard shop grease guns for fast, mess-free application across massive trailer overhauls.
The Truck-Lite 97948 formula creates an immediate, highly resilient hydrophobic barrier over exposed metal terminals, switches, and junction pins. By effectively sealing out harsh winter road brines, chemical automated wash sprays, and deep moisture, it halts oxidation in its tracks. This grease gun format allows fleet mechanics to quickly pack terminal blocks, seven-way receptacles, and open wiring systems, preventing voltage drops and unexpected DOT roadside safety violations.
The Truck-Lite 97948 Corrsion Preventative Compound, 14 oz. cartridge, is the ultimate choice for:
-
Rapidly packing large 8-terminal and 12-terminal distribution blocks (such as the Truck-Lite Model 50 Series 50800/50801).
-
High-pressure injection into tractor-trailer 7-way nose box receptacles during major fleet winterization overhauls.
-
Protecting exposed ignition blocks, battery terminals, and heavy-duty exterior trailer switches on commercial utility vehicles.
-
Alternative Sizes Available: For localized repairs or mobile service trucks, the NYK-77 formula is also offered in a 2 oz. squeeze tube (97944), an 8 oz. benchtop can (97940), and a bulk 1-quart shop can (97943).
