Discover the Molykote® range of lubricants dedicated to the automotive sector and specifically to: electrical connectors

DuPont™ Molykote^® has developed a range of Smart Lubrication™ products specifically for automotive applications. In this article, we will focus on the products used for electrical connector lubrication:

Alternative drive systems, ever more sensors and cameras everywhere, digital dashboard: more and more applications in today’s vehicles rely on plug-in connections. Electrical connectors, switches and sensors are subject to strong vibrations, frequent temperature changes as well as a large number of plugging and unplugging cycles.

To meet these demands, proper lubrication is essential to provide maximum protection of electrical connectors against corrosion and premature wear throughout the life of the vehicle, even under harsh environmental conditions.

Below is a selection of DuPont™ Molykote® lubricants already proven in the automotive industry and specifically for electrical connector lubrication:

Standard products used

Molykote^® 111 is silicone compound for gaskets and seals (silicone excluded),Sealant for outdoor equipment subject to washing and harsh environmental exposure : meters, service entrances and electrical connections. Wide temperature range. Excellent resistance to water washout.

MOLYKOTE^® 4 is used for lubrication of cable connectors, battery terminals, rubber door seals, switches, plastic and rubber Orings automotives ignition systems and sparkplug connections, cutoff circuits in electric wiring systems and connections.

MOLYKOTE^® 5 is a thermal and dielectric grease that helps prevent electrical arcing and flashing on insulators and bushings. It is also suitable for preventing rust and corrosion on insulator threads and bolts. To help prevent arcing and flashing on insulators and bushings.

Additional requirements
