Frequently Asked Questions

Q: What is dielectric silicone grease used for?

A: Dielectric silicone grease is a non-conductive silicone paste used to insulate and protect electrical connections, spark plug boots, high-voltage components, and terminals from moisture, corrosion, and arcing. It is also used as a lubricant for rubber O-rings, seals, plastic parts, and metal surfaces in plumbing, marine, and automotive applications.

Q: Is this silicone grease safe to use on rubber and plastic?

A: Yes. This silicone grease is specifically formulated to be compatible with rubber, plastic, and metal surfaces. It is non-corrosive and non-irritating, making it safe for use on O-rings, gaskets, seals, and a wide variety of plastic and rubber components without causing degradation.

Q: How much product comes in each tube?

A: Each tube contains 5g of high-pressure silicone grease. You can choose from pack sizes of 1, 2, 3, 5, or 10 pieces to suit your needs — whether for a single repair or stocking a workshop or toolbox.

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

A: No. This silicone grease is non-curing and non-volatile, meaning it will not harden, dry out, or evaporate over time. It stays pliable and effective, maintaining its protective and lubricating properties for the long term.
