Multipurpose Silicone Grease & Lubricant – 4 oz Squeeze Tube
One tube of crystal-clear silicone grease solves dozens of shop headaches
From squeaky O-rings to flickering trailer lights, high-purity silicone grease is every tech’s go-to for waterproofing, dielectric sealing, and long-life lubrication where petroleum products fail. Our easy-to-dispense 4 oz squeeze tube delivers a transparent formulation that stays put in sub-zero winters and 400 °F engine bays alike—perfect for pros, DIYers, and fleet managers who want a single compound that just works across rubber, plastic, and metal.
Why dedicated silicone grease beats “all-purpose” grease every time
-
100 % water-repellent —forms a hydrophobic barrier that blocks rust and wicks moisture from connectors.
-
Wide temp span (–40 °F → 400 °F) —never hardens in January or drips in July.
-
Dielectric strength > 25 kV/mm —insulates spark-plug boots, coil packs, and trailer plugs.
-
Rubber & plastic safe —will not swell EPDM, nitrile, Viton®, or degrade PVC housings.
Result: longer seal life, cleaner electrical signals, and zero petroleum goo to scrape off next service.

Where silicone grease shines (and where it doesn’t)
| Use-Case | Why it works | Pro Tip |
|---|---|---|
| O-rings & pump gaskets | Maintains elasticity, prevents dry-rot | Light smear; wipe squeeze-out |
| Spark-plug boots & COP coils | Stops arcing, eases future removal | Coat inside boot only |
| Battery terminals & fuse blades | Seals out salt mist; prevents white fuzz | Pair with our Battery Terminal Grease Kit for felt-washer protection |
| Brake caliper slide pins | Lubricates without swelling rubber boots | Clean old petroleum grease first |
| Marine & RV electrical plugs | Blocks corrosion in harsh environments | Reapply each season |
| Do NOT use on | Wheel-stud seats, oxygen lines | Choose Anti-Seize or oxygen-safe grease instead |
Three-step application in under a minute
Clean & dry the surface—remove dirt, old lube, or corrosion.
Dispense & spread a paper-thin film of silicone grease. A little goes far; excess wipes away.
Assemble the parts. Enjoy waterproof, friction-free service for seasons.
Shop Hack: Keep a trim plastic pick or hobby brush nearby to work the grease into Deutsch or Weather-Pack connectors.
