  • Dependable Sealant and Adhesive: A Review of J-B Weld 31319 Black RTV Silicone Sealant
Color: Black Size: 3 Ounce
I recently had the opportunity to use the J-B Weld 31319 Black RTV Silicone Sealant and Adhesive, and I must say, I am thoroughly impressed with its performance and versatility. As someone who frequently tackles DIY projects and repairs around the house, finding a reliable sealant and adhesive is essential, and this product certainly delivers. One of the standout features of the J-B Weld 31319 is its exceptional durability. Once applied, it forms a strong and resilient bond that withstands a wide range of environmental conditions, including temperature fluctuations, moisture, and vibration. Whether I'm sealing gaps in plumbing fixtures or bonding materials together, I can trust that this silicone sealant will hold up over time. Another aspect of this product that I appreciate is its ease of use. The nozzle allows for precise application, minimizing waste and mess during the sealing process. The consistency of the sealant is ideal—not too runny, yet smooth enough to spread evenly and fill in cracks and gaps effectively. Cleanup is also a breeze, as the excess sealant can be easily wiped away with a cloth or sponge. The black color of the sealant is a nice touch, especially for applications where aesthetics are important. It blends seamlessly with dark surfaces, providing a clean and professional finish that enhances the overall appearance of the project. Furthermore, the versatility of this product makes it a valuable addition to any toolkit. Whether I'm sealing leaks in automotive components, repairing household appliances, or even crafting custom projects, the J-B Weld 31319 proves to be a reliable solution time and time again. In conclusion, I can wholeheartedly recommend the J-B Weld 31319 Black RTV Silicone Sealant and Adhesive to anyone in need of a dependable sealant and adhesive for a variety of applications. Its durability, ease of use, and versatility make it a standout product in its category, and I will certainly continue to rely on it for all my sealing and bonding needs in the future. ... show more

Read the description. It does exactly what it says. I've never found a cheaper replacement that matches the quality. Highly recommended! ... show more

  • Good
Color: Ultimate Black Size: 3 Ounce
I used this on this for a valve cover gasket and it worked alright. The tube basically blew out the back end when squeezing so be careful. But other than that it was fast easy and dried quick, which is what I needed. It’s as easy to remove as most siliocine caulkin. And it stuck pretty good. You get a decent amount per tube. More than you could ever need for 1-3 jobs. And the color was what I needed, but if you’re using this like you should, the color should matter as it’ll be hidden for the most part. Over all, it’s good but I which the actual tube it’s held in was More durable, no reason it should bust open just from squeezing it. But the size is good, you get a lot of it. ... show more

  • Great RTV for use when oil exposed
Color: Ultimate Grey Size: 3 Ounce
I had to change the valve cover in my ALH diesel motor. The replacement requires a high quality RTV in four specific locations. I’ve always been a fan of JB Weld products so I gave this a shot. It hasn’t let me dow. I got 2500 miles now on the new valve cover and nary a drop of oil is leaking.

  • Works as it should
Color: Clear Size: 3 Ounce
Used this to fill in holes on my homemade solar charged 12v battery pack. Squeezes out of the tube easily and seals very well but is nice and thick. Color is clear and clean. There's not an extremely overpowering scent. Seems like it will work well and last a long time.
