Would this work to glue it back in?** A: Be careful of sealant giving off toxic fumes the first few times you use it. Try heating up the oven 2-3 times before actually placing food inside that could absorb the toxic off-gasses. **Q: Would this be a good product for sealing a crack in a dishwasher liner?** A: Yes- I did this, along with filling in a gap on the dishwasher door gasket (which was ultimately replaced). Worked great! Be sure to clean the surface and rough it up a little (a bit of sandpaper, then clean the sandpaper dust off before application of the RTV). Used it a few years ago- is still sealed; all is well. **Q: Can I use it to glue shower mirror to tile in my shower** A: I wouldn't use it for that purpose myself. I qouls suggest an industrial caulking-type adhesive such as Loctite or Tough As Nails. **Q: Can you remove it if needed?** A: Believe the instructions are on the back side of the package. You can use acetone or paint thinner to remove.Its great stuff. Works well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great to make automotive gaskets *by on Reviewed in the United States May 14, 2026* This is pretty good stuff. I bought it to make the china wall gaskets on the ends of my sbc intake. And it works really good. No more leaks. I have always used the grey right stuff rtv. But this has a higher heat rating. So I decided to try it. And it works great ### ⭐⭐⭐⭐⭐ Works Great on my Steam Iron Repair *by on Reviewed in the United States June 9, 2026* Excellent Heat Resistance! Be sure to let it fully cure before putting it through its paces.I used this one inside my wife's 25yr old Steam Iron where the water tank gromets passing water to the hot plate finally gave out. She loves her old Iron and I love her, so the effort was well worth it. ### ⭐⭐⭐⭐⭐ This really works well. *by on Reviewed in the United States January 30, 2026* So this was a longshot. I have a hair dryer with a diffuser. Every time I use it the diffuser goes flying off. It's hot where it clips on. So I tried a bead of this glue and the diffuser is now permanently glued to the hair dryer and will not come off. It was the PERFECT glue for this application. It would be good for anywhere you need glue that gets hot -- like a stove gasket. Great product. ## Frequently Bought Together - J-B Weld 31314 High Temperature RTV Silicone Gasket Maker and Sealant - Red - 3 oz. - 1/4" ID Silicon Tubing, JoyTube Food Grade Silicon Tubing 1/4" ID x 3/8" OD 10 Feet High Temp Pure Silicone Hose Tube for Home Brewing Winemaking - ANPTGHT 1/4” Thru-Bulk Bulkhead Plastic Hose Barb Fittings Union Adapter Fittings for Aquarium Fuel Gas Liquid Air with Metal washers (Pack of 6) --- ## 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.tn/products/17058346-j-b-weld-31314-red-high-temperature-rtv-silicone-gasket](https://www.desertcart.tn/products/17058346-j-b-weld-31314-red-high-temperature-rtv-silicone-gasket) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-16*
