Regards Vijay Kumar** A: The #22 HD tape is for making common electrical splices/protection. It is "thin" and should not be stretched when applied to finish - always "cut" the tape, then finish the last wrap. This provides OK weather proof, if applied in 2 or more layers, that over-lap each other by 1/2 the width. Whereas:The #23 tape is a much thicker and "rubber" vs a plastic - it is spongy when applied. This tape is called self amalgamating which means it loves to STICK to ITSELF and forms a true moisture barrier when laid on carefully using that 1/2 width overlap. It should be "protected" from the elements by a layer of the #22 plastic tape to finish the splice correctly. It also provides extra voltage protection for high voltage wires - ie, 2 or 3 layers of this should stand up to 2500 to 7000 volt mains service, whereas the #22 tape is only good for up to 600 volt service. Thickness is used for increased voltages.I am a ham radio person, NOT a lic electrictrician so consult a professional if you need more understanding. **Q: Can I use this to repair wire insulation on my car where I can't use shrink tubing?** A: You might find this tape bulky for that application. Temperature to 194F so not all engine locations. I do not know about resistance to fuel and oil. **Q: Good for garden hose repair?** A: I've used it on multiple applications with great results but have never to repair a hose. I'd be curious to see how that goes. Depends on the leak? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Only Way to Insulate Outdoor Electrical Connections *by on Reviewed in the United States May 2, 2026* Excellent product for waterproofing electrical connections. Have used this to waterproof extension cords used outdoors all winter and for coaxial cable connectors. Proper procedure: first wrap connection with good electrical tape, a layer of this product, and a final layer of electrical tape. You will not get any water ingress and the connections will be pristine if you ever need to separate the connections. ### ⭐⭐⭐⭐⭐ Quality and Fitment *by on Reviewed in the United States February 6, 2026* Great for Highlander Hybrid Battery Sealing - Needs Heat!I bought this to seal the frame of my Highlander’s hybrid battery to prevent air leaks, similar to the strong OEM tape. At first, I was disappointed because it didn't seem to stick at all. However, after some research, I learned that this type of tape works best with pressure, stretching, and a bit of heat.I used a hair dryer to warm up both the surface and the tape itself, and then it bonded perfectly. For my specific purpose, it’s a great product. I wanted to share this tip in case anyone else runs into the same issue! ### ⭐⭐⭐⭐⭐ There really is nothing else like this... *by on Reviewed in the United States July 26, 2025* There really is nothing else like this....it's not cheap, but it really works. I tend to use it for bicycle-based applications but for whatever you need, this stuff works. I love how it can stretch and flex but still hold its tension/stickiness when applied. For my uses, one roll lasts me a long time. ## Frequently Bought Together - 3M Scotch Rubber Mastic Tape 2228, 1 in x 10 ft, Black, Conformable, Self–Fusing, Electrical Insulating, Moisture Sealing, Indoor and Outdoor Applications, 65 mil thick, 1 Roll - 3M Scotch Rubber Mastic Tape 2228, 2 in x 10 ft, Black, Conformable, Self–Fusing, Electrical Insulating, Moisture Sealing, Indoor and Outdoor Applications, 65 mil thick, 1 Roll - 3M Scotch Vinyl Electrical Tape Super 88, 3/4 in x 44 ft, Black, 1 roll, Premium Grade, Rubber Resin Adhesive, PVC Backing, All-Season Heavy Duty Electric Tape --- ## 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.sg/products/7982098-3m-scotch-rubber-mastic-tape-2228-1-in-x-10](https://www.desertcart.sg/products/7982098-3m-scotch-rubber-mastic-tape-2228-1-in-x-10) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-25*
