Grote 99170 Ultra Seal Corrosion Preventative Sealant – 4 oz. Tube

Ultimate Protection for Critical Connections Electrical failure caused by corrosion is one of the leading causes of vehicle downtime. The Grote 99170 Ultra Seal is a specialized, non-conductive grease designed to seal out moisture, salt, and road chemicals. By applying Ultra Seal to your trailer connectors, bulb contacts, and wiring harnesses, you create a robust barrier that prevents the "green rot" of oxidation, ensuring your lights stay bright and your sensors stay active.

Superior Non-Conductive Performance Safety and precision matter. Grote Ultra Seal boasts a 25% higher non-conductivity rating than leading competitors, making it exceptionally safe for sensitive electronic circuits and multi-pin connectors. Its high dielectric strength prevents arcing and short circuits, even in high-vibration applications.

Engineered to Stay Put Unlike standard dielectric greases that can thin out or wash away, Grote 99170 is formulated with specialized tackifiers. These additives improve adhesion to metal surfaces and provide elite resistance to high-pressure washouts. Whether you're operating in heavy rain or cleaning your rig with a power washer, Ultra Seal stays in place to provide continuous protection.
