Permatex Dielectric Tune-Up Grease Squeeze Tube 9g

Keep your electrical connections protected with Permatex Dielectric Tune-Up Grease Squeeze Tube 9g. This is the go-to grease for sealing out moisture, salt and road grime so your vehicle’s electrical system stays reliable. By keeping current where it belongs, it helps reduce misfires, flickering bulbs and those annoying intermittent faults—exactly what you want, whether you’re doing a quick tune-up or chasing a stubborn connection on a modern high-energy ignition system.

Applied as a thin film, it forms a protective barrier on spark plug boots, coil and sensor connectors, bulb sockets and trailer plugs. That barrier helps prevent voltage leaks and corrosion, so components last longer and perform consistently. A light smear inside plug boots also stops them from bonding to the plugs, making future plug changes faster and less frustrating.

The compact 9g squeeze tube slips easily into your toolbox or glovebox and lets you put the grease right where you need it with minimal mess—plus a little goes a long way. If you want dependable starts, brighter lights and fewer electrical gremlins, this dielectric tune-up grease is a simple, smart upgrade for your vehicle.
