MOLYKOTE Specialty Lubricants for HV connectors Lubricants for high-voltage connectors to ensure proper sealing performance and consistent electrical conductivity over time Ensure reliability of high-voltage connectors in EVs The number of high-voltage connectors in electrified vehicles has increased significantly. Functionality of these connectors is key to ensuring smooth operation of the car. Moisture creep-in is prevented by an elastomer seal. This seal needs to be lubricated to avoid microcracking during assembly and to simplify assembly in general. MOLYKOTE 111 Compound and MOLYKOTE HP-300 Grease perfectly meet this need and provide additional sealing performance due to their excellent resistance against water. Both products have high dielectric strength and will retain their functionality in high-voltage environments. Additionally, the seal's metal pins require lubrication to ensure consistent electrical conductivity over time. MOLYKOTE L-8030 Semi-Dry Lubricant minimizes wear and fretting corrosion caused by vibrations and results in lower insertion force while protecting metal from oxidation. Tests in the field showed no change in electrical conductivity, as well as consistent friction values over 250+ mating cycles, when MOLYKOTE L-8030 Semi-Dry Lubricant was used. High dielectric strength & good elastomer compatibility Specification writers: These values are not intended for use in preparing specifications.
