J-B Weld 31314 Red High Temperature RTV Silicone Gasket Maker and Sealant - 3 oz.

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

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.

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.

The rubber seals on my car windows were coming loose. After applying this adhesive and exposing them to high temperatures in the sun, they haven't come loose again.

Work really good seal just right very tight.

Good quality

Used to replace an SV’s gasket gone bad - clear instructions and good technique stopped my leak. Still have loads left but been about a week and no fault. Ensure you buy the heat resistant version if you’re using it on engine parts.

Bought this to fix the inner and outer glass of my electric oven door. Been looking for one at the local hardware stores but didn’t find one. Purchased this since it’s mentioned for glass and oven doors and suitable for high temp applications. Worked great and baked a few cakes since - all good. Just has to take note that it takes about 24 hours to complete heal.

I had to rebuild and repair an old 1940s copper diesel tank, the original cork gasket was disintegrated so I used this to make a seal around the hatch and after two months of use it seems to be holding its own. I’d buy again if required.
