Frequently Asked Questions

Q: What is dielectric silicone grease used for?

A: Dielectric silicone grease is used to insulate, protect, and waterproof electrical connections, high-voltage components, spark plug boots, marine connectors, and plumbing O-rings. It prevents arcing, moisture ingress, corrosion, and rust while also functioning as a lubricant for rubber, plastic, and metal surfaces.

Q: Is this dielectric grease safe for rubber and plastic components?

A: Yes! This silicone-based grease is completely safe for use on rubber O-rings, plastic housings, and metal parts. It will not degrade, swell, or damage these materials, making it ideal for plumbing, automotive, marine, and electronics applications.

Q: Will this grease dry out or harden over time?

A: No. This is a non-curing, non-volatile silicone grease, meaning it stays soft, pliable, and effective indefinitely. It will not dry out, crack, or evaporate, ensuring long-lasting protection even in high-temperature or outdoor environments.

Q: How much grease is included in one unit?

A: Each unit contains 5g of high-pressure silicone grease, packaged in a convenient applicator. This is ideal for small-scale electrical maintenance, O-ring lubrication, or spot protection tasks.
