    Loctite Dielectric Tune-Up Grease, 3-Oz Tube

    Part #: LT-37535

    Loctite 495549 (LB 8423™) Dielectric Tune-Up Grease is a silicone-based, high-performance dielectric lubricant designed to protect electrical connectors by forming a moisture-proof barrier, preventing voltage leakage, and ensuring robust spark in high-energy ignition systems. It also acts as a lubricant for rubber, plastic, and ceramic surfaces, and remains stable across wide temperature ranges — from –67 °F to +399 °F — making it suitable for automotive, marine, and industrial environments.
