AGS has been formulating and manufacturing professional-grade automotive chemicals in the United States for over 90 years. Every can of AGS Dielectric Grease reflects decades of real-world expertise — quality you can rely on, built right here at home.

At 4oz, AGS Dielectric Grease gives you up to four times more product than competing 1oz tubes at the same price. Protect every connector, terminal, and spark plug boot in your vehicle without running out mid-job. More coverage. Less restocking.

Forget squeeze tubes that waste product and create a mess. The AGS brush-top lid gives you complete control — apply exactly the right amount, exactly where you need it. Clean, efficient, and professional-grade every time.

From arctic cold starts to scorching engine compartments, AGS Dielectric Grease maintains its protective seal across every extreme. Moisture, road salt, and intense heat won't break down this formula — it holds up where others fail.

AGS Dielectric Grease protects spark plug boots, battery terminals, wiring harnesses, ignition coils, fuse boxes, trailer connectors, and O-rings. Non-conductive and safe for rubber, plastic, and metal — one can covers your entire vehicle.

From the shop floor to your garage, AGS Dielectric Grease is the compound professional technicians reach for first. The silicone formula seals out corrosion, prevents voltage leakage, and extends the life of every electrical connection it touches.

AGS Dielectric Grease delivers four layers of proven protection: a waterproof silicone moisture barrier, non-conductive voltage integrity, material-safe formulation for rubber and plastic, and extreme durability from -40°F to +400°F. Professional-grade science in every can.
