Description
Dielectric Grease – 4 oz Brush-Top
4LifetimeLines Dielectric Grease is a high-purity silicone compound designed to protect electrical connections from moisture, corrosion, and environmental damage. By forming a non-conductive barrier, it helps prevent voltage drop, arcing, and oxidation in automotive and electrical applications.
This dielectric grease resists extreme temperatures and harsh conditions, making it suitable for use year-round in automotive, marine, and outdoor environments. Its stable silicone formula will not melt, harden, or break down when exposed to heat, cold, water, or common automotive chemicals.
Designed for Electrical Protection
Formulated specifically for electrical use, this dielectric grease provides excellent insulation and helps prevent moisture intrusion in spark plug boots, ignition coils, battery terminals, connectors, and sealed electrical plugs. When applied correctly, it will not interfere with sensors or electrical signals.
Wide Temperature & Chemical Resistance
With a service temperature range from -40°F to 400°F, this grease remains stable in extreme climates. It repels water, salt, and chemical contaminants while maintaining rubber and plastic elasticity to help extend the life of seals, grommets, and O-rings.
Convenient Brush-Top Packaging
The 4 oz jar includes a built-in brush applicator for precise, mess-free application. This shop-size container provides enough product for hundreds of connections, making it ideal for both professional technicians and experienced DIYers.
Versatile Applications
Common uses include spark plug boots, ignition coils, battery terminals, fuse blades, relay pins, trailer connectors, and weather-sealed electrical plugs. A thin film is all that’s needed to provide long-lasting protection.
Backed by the 4LifetimeLines warranty, this dielectric grease delivers reliable electrical protection and long-term performance in demanding conditions.
