Product Details

Permatex Dielectric Tune-Up Grease is a silicone dielectric compound used to insulate, lubricate and protect electrical fittings. It protects against salt, dirt, moisture intrusion and stray current in electrical connections.

Dielectric grease extends bulb and housing life of navigation lights, masthead electrical connections, trailer lighting and harness or any electric connections exposed to moisture and the elements. Prevents voltage leakage around any electrical connector thereby insuring a strong spark in high energy engine ignition systems.

Info & Guides
The compound is an excellent lubricant on rubber, plastic and ceramic surfaces and it also has good high temperature properties, thus preventing fusing of connections.

Seals and protects
By Moonbat from Bellflower, Calif

Dielectric grease does a superior job sealing out moisture from any and all kinds of electrical connections. It does a great job on trailer wiring and lighting connections. This stuff does the job.

Bottom Line Yes, I would recommend to a friend
