Designed to mold effortlessly into cracks and pinholes on pipes and hoses, it provides a reliable seal for air and steam leaks. Compatible with metal, plastic, and rubber, it works best when reinforced with E/Fusing tapes, making it a must-have for professional-grade plumbing and emergency fixes. ## Description MIDSUN E/FUSING 900 is a silicone putty for use in cracks and voids in damaged pipes or hoses. Molds easily into small cracks or pinholes on pipes or rigid hoses. Excellent assistance in sealing air and steam leaks with other E/Fusing tapes. Review: Excellent moldable putty! Used it for the water fountain and it has held up great! Review: I recently purchased a YoloTek GoPro Powerstick. That unit is supposed to come with a very small amount of their silicone rainproof putty to wrap around the wire connection on your GoPro in order to keep rain/water out. Unfortunately, they seem to be having some issues; as seen by many reviews, a lot of their Powerstick packaging doesn't in fact come with the rainproof putty like it advertises (which I believe has been proven to have been an honest mistake on their part, which they do attempt to make right with their customers once it's brought to their attention). And buying it separately is just ridiculous due to its high pricing (~$30.00 per box, last time I looked). This E/Fusing 900 here works phenomenally as a replacement. It doesn't dry up (even on a hot, Florida summer afternoon) and its consistency remains the same. It's very easy to work with and creating a functional seal around your GoPro wire connection(s) takes little effort. And, one of the best things? You get a significant amount of this stuff; more than I'll ever need for my multiple GoPro's (the photo of the roll in my hand is what was left after I used it to generously seal up one GoPro in two spots on the Powerstick). All at a price that equates to half of what YoloTek charges for a box of their rainproof putty (which they only supply a small amount compared to how much of this E/Fusing 900 that you get). This stuff has many different uses, but it has just knocked it out of the park for my purpose. The only cons that I've encountered so far: 1. If you're not familiar with how to successfully waterproof an electronic device (as opposed to making it water resistant), you can kill a GoPro or another device. Of course, this is entirely based upon the user and the E/Fusing 900 is not at fault for it. I just believe that it can give a sense of false security to those that look at it incorrectly. A great example to give you here is with my GoPro that you see in the photo that I uploaded. It's a GoPro 8 with a new battery door on it that allows for the USB power cord to be plugged in. This new battery door is not waterproof. Some are, and some aren't; mine isn't. Some users have killed their GoPro's by thinking that they've waterproofed the unit by applying the E/Fusing 900 (or in their case, the Yolotek silicone putty or something similar) like I have, which is not the case. It is simply water resistant. If submerged, water will enter the cracks of the battery door and kill the GoPro. Again, this ultimately is user error, but worth bringing to your attention if you're wanting to use it for the same purposes as I have. 2. After handling the YoloTek silicone putty that one of my friend's bought, it is easier to work with, but not by much. 3. The color might not be appealing to some people. This is where the clear YoloTek silicone putty can outshine the E/Fusing 900. I don't mind at all, personally. Especially since options appear to be so limited. Good luck with your projects, everybody! ## Features - Made in USA - Mold into pinhole leaks on pipelines to assist in leak sealing - Use E/Fusing 140 or E/Fusing 330 to wrap and reinforce seal - Package weight of the Product: 265 Ounces ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RV5R33Y | | Brand Name | E/FUSING | | Color | tan | | Compatible Material | Metal, Plastic, Rubber | | Container Type | Tube | | Customer Reviews | 4.4 4.4 out of 5 stars (1,025) | | Item Form | Putty | | Item Package Quantity | 1 | | Item Weight | 0.1 Pounds | | Manufacturer | Midsun Specialty Products | | Material Type | Silicone | | Model | E/FUSING 900 | | Other Special Features of the Product | moldable and self-fusing | | Specific Uses For Product | Repair | | UPC | 764759609005 | | Volume | 2.5 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** E/FUSING - **Item form:** Putty - **Material:** Silicone - **Special features:** moldable and self-fusing - **Specific uses for product:** Repair ## Images ![E/FUSING 900 Moldable Silicone Putty - Image 1](https://m.media-amazon.com/images/I/71YnqOHkBHL.jpg) ## Questions & Answers **Q: Does it become hard once set? Wanting to use as a mother mold** A: It never sets - it remains soft and pliable. I would use hydrocal for the mother mold or reinforced fiberglass with epoxy. **Q: Does this cure flexible or rigid?** A: This product does not cure at all. It remains pliable indefinitely **Q: Does this putty maintain its shape once molded, like modeling clay, or does gravity cause it to melt back down?** A: Yes and it was very easy to work with. it did not stick to you hands and you could mold it very easy. **Q: Wrap around outdoor speaker wire (binding post connection) for additional waterproofing? Want something removable for winter storage of speakers.** A: This is potentially messy for that application. Try using E/FUSING 112 to wrap wires to protect them from elements. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***R on 13 May 2025* Excellent moldable putty!
