One of the best and most affordable brands high temp RTV silicone. I use it for ceiling fittings on liquid culture jars used for mycology so they can be sterilized in an autoclave with no problem. Works great keeps a great seal and easy to use.

Purchased this to use on my dirt bike header pipe. Sealed up great and was better than other solutions I tried.

Great stuff for what I need it for. I use it in mushroom cultivation. To seal jars and use as injection ports. I recommend to anyone doing the same. Easy to use great price. Durable up to 500°. I use in boiling water no leaks. Easy cleanup

This good product and high-quality I didn’t expect it that big it’s enough to make seal with 6 different cars

I use this stuff on everything......it works great !!!

I use this on my custom built exhaust systems and never any exhaust leaks.

This is a good high temp silicone. Great for making gaskets. I've used it before and it is a good product.
