Dielectric Grease vs. Vaseline: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on December 26, 2023
Dielectric grease is a silicone-based lubricant used for electrical insulation; Vaseline is a petroleum jelly used for skin protection and lubrication.

Key Differences

Dielectric grease is a silicone-based lubricant that does not conduct electricity, making it ideal for sealing and protecting electrical connections. Vaseline, a brand name for petroleum jelly, is primarily used for skin care and minor cuts, although it can also serve as a general lubricant.
