The silicone grease part, yes. The dielectric part, no. There is a silicone grease meant specifically for the slides on brake calipers. This is not it. **Q: How thick is the grease? Would you say as thick as wheel bearing grease or maybe vasoline?** A: Yes - very similar in viscosity to either vaseline or bearing grease. I absolutely love this stuff, my boat mechanic had recommended a few years back to me and I keep tubes in the garage and on the boat. Quality grease that is synthetic and won't react or break down insulation, great for crimp terminations and electrical joints in general - highly recommend **Q: Would this be useful for electrical contacts in a marine environment?** A: Useful yes, but not the best choice. If you use Super Lube #21030, it will do just as well as #91003. The difference between these two is their compatibility with certain plastics and rubbers. Really though, the best product for you would be Super Lube #82003 or #82016 (those two are the same "stuff", one is 3 oz tube, the other is a little "bucket" of 400g). Those are specifically designed to be used as connector gel. **Q: Can this be used to grease e-bike hub motors?** A: Dielectric Grease is protection from corrosion, Not a lubricant to speak of. I would say No to your application....but I could be wrong. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well and a lot cheaper than specialized vacuum grease *by G***X on 6 February 2026* ### ⭐⭐⭐⭐⭐ 屋外、悪環境、電気電子製品の接触部には、 これですね。 *by よ***ん on 29 April 2021* 屋外用電子デバイスの接点絶縁(microSDカード)するために購入しました。さすが、こういった化学製品は、欧米にしかないでしょう。早急な対応ありがとうございました。 ### ⭐⭐⭐⭐⭐ Great product! *by F***R on 29 October 2025* ## Frequently Bought Together - Super Lube 91003 Silicone High-Dielectric and Vacuum Grease, 3 oz. - Super Lube Silicone O-Ring Grease Non-Curing Compound (Translucent White, 3oz Tube) | NSF Certified Food Grade & Clean | Heat Stable - Super Lube-21030 Synthetic Multi-Purpose Grease, 3 Oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/296538499-91003-silicone-high-dielectric-and-vacuum-grease-model-91003](https://www.desertcart.us/products/296538499-91003-silicone-high-dielectric-and-vacuum-grease-model-91003) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
