Ideal for use on spark plug boots, distributor cap nipples, battery terminals, ignition coil connectors, and trailer electrical connectors, LOCTITE® LB 8423 is a high-viscosity silicone dielectric compound paste to facilitate and improve tune-ups. It also prevents voltage leakage around any electrical connector, thereby ensuring a strong spark in high-energy ignition systems. The compound also works amazingly well on rubber, plastic, and ceramic surfaces. It has great high-heat properties with non-compromised performance at temperatures up to 204°C (400°F), thus preventing the fusing of spark plug boots to the spark plug itself.
