Review: Works great at stopping Oil Leaks - Used this to stop that tiny drip of oil from the drain plug on my Harley Davidson. I had tried 3 times replacing the o-ring as well as putting pipe tape on the drain plug threads but still had that annoying tiny drip under my bike. Not any more, Great stuff, Highly recommended!!! Review: Works well, very well... - I've used this product on rear differential gaskets, valve cover gaskets, intake manifold gaskets, and water pump gaskets and it works very well. In my mind the main advantage is the fact that it's non-hardening, which means that in 3 years when you have to dis-assemble the the engine, or rear end, or whatever, gasket removal is MUCH easier than with a hardening or a glue type product. I've also used the Hylomar spray and it works just as good as the tube, but much easier to apply over a larger area. ## Features - One Tube of Hylomar Universal Blue 10098 - 3.5oz - 100 grams - Non-setting and Non-hardening - Resistant to a wide range of fluids including all industrial fuels, oils, water, and brine ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NJHZJQQ | | Best Sellers Rank | #203,656 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #179 in Industrial Joint Sealants | | Brand | Hylomar | | Color | Blue | | Date First Available | February 8, 2019 | | Item Form | Paste | | Item Weight | 3.5 ounces | | Manufacturer | Hylomar | | Material | Silicone | | Number of Items | 1 | | Style | Industrial | | Unit Count | 3.5 Ounce | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Hylomar - **Item Weight:** 3.5 Ounces - **Material:** Silicone - **Style:** Industrial - **Water Resistance Level:** Water Resistant ## Images ![Universal Blue Non-Setting Sealant Silicone Jointing Compound 3.5oz - Image 1](https://m.media-amazon.com/images/I/419-ph9wIfL.jpg) ## Questions & Answers **Q: Hylomar's website shows that this is made in 3 different viscosity grades, light, medium, and heavy. What's being sold here?** A: hi. I checked the tube and the package. Does not say anything about viscosity. Seems pretty thin, same stuff I have been using for over 20 years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great at stopping Oil Leaks *by D***H on October 10, 2023* Used this to stop that tiny drip of oil from the drain plug on my Harley Davidson.
