A must for all electronic and standard ignitions

Works on high energy ignition systems

Seals out moisture and corrosion

Keep Your Electrical Components Waterproof and Protected: Dielectric grease is the perfect solution for keeping your electrical components safe from moisture and corrosion. Our brush top applicator makes it easy to apply the grease exactly where it's needed.

Long-Lasting Protection Against Oxidation, Corrosion, and Contamination: Our dielectric grease forms a thick, waterproof layer that prevents oxidation, inhibits corrosion, and keeps out dirt, salt, and other contaminants. It's non-melting so it will stay in place even in extreme conditions.

Multipurpose Silicone Lubricant: Our silicone lube is perfect for a variety of automotive, electrical, and marine applications. It's compatible with metal, rubber, and plastic and is great for fixing sluggish car windows.

This material has strong adaptability, wide application range and high oil content. Scope of application: electrical equipment, automobiles, automobile sealing strips, sunroof tracks, ships, household appliances and hardware accessories

It can play a very good role in insulation, sealing and lubrication. It is very suitable for power cable joints, switch accessories and battery terminals to prevent corona discharge and eliminate arc. It can also prevent water and dust from entering

Clean up the parts that need lubrication before use. The tools worn by the product can help you spread it evenly where you need it

Silicone high-dielectric and vacuum grease SG01, translucent white, non-toxic, odorless and non-irritating. Safe and environmentally friendly. Compatible with most plastics and rubbers. Waterproof and protects against moisture and oxidation. Excellent lubrication and long-lasting even in wet environments.

Protect electrical connections wiring from salt, dirt and corrosion. It will prevent voltage leaks around any electrical connection. For example extend the life of bulb sockets, prevent spark plugs from fusing to boots and improve electrical performance.

Dielectric silicone grease can be applied in marine and automotive electrical connection, trailer hitches and battery terminal. Ideal for vacuum systems, garden hoses and seals. Reduce the overall leak rate in vacuum applications by filling the spaces of the gland’s surfaces and lowering permeation rates of the elastomer.

Lithium grease, cleaning/deoxidizing, precision lubrication, oxidation/corrosion protection, excellent wear and pressure resistance, high dripping point, Temps; -40 to 260 C.

Graphite particles: Graphite particles assist in heat stability and lubrication. Graphite is excellent for heat transfer. Other particles available; without particles, copper, aluminum, quartz, graphite/quartz and Teflon.

Provides cleaning/deoxidizing and additional protection; Infused with DeoxIT Dx100L, which allows the fluid to mechanically bond to the metal surfaces. It cleans surfaces over time and coats and re-coats, even when surfaces are disturbed (vibration or mechanical movement). It is a non-conductive fluid that enhances conductivity. No other grease does this!
