Weatherproof Protection for Every Connection
When it comes to protecting your vehicle’s electrical systems, ordinary grease won’t cut it. Permatex Dielectric Tune-Up Grease is engineered to seal out salt, moisture, and grime—defending your connections against the elements that cause shorts, corrosion, and failures.
From spark plugs to trailer wiring, this high-performance dielectric grease ensures safe, stable current flow in any weather. Whether you're servicing your daily driver, maintaining marine electronics, or outfitting off-road gear, Permatex delivers versatile protection that performs under pressure.
Wherever there’s a connection, Permatex keeps it clean, secure, and firing on all cylinders.
Protect and Perform — In Any Condition
Built to Withstand the Elements
Rain, salt, dirt, or snow — Permatex keeps your electrical connections sealed and protected. No more failures caused by corrosion or moisture.
Works Across Vehicles & Equipment
Whether you're tuning up a car, boat, ATV, or mower, this grease applies easily to spark plugs, terminals, and wiring.
Reliable, Long-Lasting Electrical Safety
Prevents voltage leaks and misfires with a high-performance dielectric barrier. Keeps your electrical systems running smoothly and safely over time.
Step by Step
Simple and Easy
Applying Permatex Dielectric Grease is quick, clean, and essential for long-term electrical performance. Just apply a small amount of grease inside the boot or wiring, spread it evenly, and reconnect. This forms a moisture-resistant barrier that prevents arcing, corrosion, and misfires — even in extreme weather conditions.
