Food Grade NSF FDA RTV Silicone Sealant Adhesive Red High Temp 10.3oz (Standard Version) (Standard Version)

Used for a bbq pit. Workes like a charm

The bottom of my oven developed a couple of small holes from crinkling from thermal shock, so it was not holding its temperature very well. But this sealed up the holes easily and my oven holds its temperature once again! I originally bought this a couple of years ago and simply reapply it every six months. It lasts a long time! As for someone mentioning that its food safety is questionable because they only saw it on a sheet of paper, it has the NSF logo right on the bottle.

This is a really neat product and works perfectly to seal exhaust leaks on your car. Highly recommend even with the higher price. After tons of research this was the right choice and has held firm with its sealing and high temperature working ability. Use gloves, this will get on anything and everything and stain it permanently.

Good buy easy to use has worked on my smoker great

Easy to apply. I like that the tube was molded closed and you cut the plastic away to open the nozzle. This is much better than the caulk tubes that are sealed with foil. Doesn't smell, I used it indoors without issue. Adheres very well on vertical surfaces. You get about 10 minutes of working time if you need to tool it around to get the right coverage or thickness then it skins over. Bottle says it fully cures in 24 hours.

This is the BEST sealant I've ever used. It's the super glue of sealants. It's FOOD SAFE. You don't need much to adhere smooth surfaces, even to smooth concrete. It's got a STRONG vinegar smell which goes away in a day or so It ain't cheap but it's the moral high ground if working around water, sinks, kids, anyone concerned about chemical safety and should ensure no call backs. If using in finished area you'll need to hold back and cover over once cured with something more decorative than it's screaming orange red color. I say hold back rather than just paint over, as any peeled paint will leave a GLARING problem and call back.

I bought this product specifically for its food grade application and it’s high temperature rating. It worked perfectly for my application. It does have a strong odor until it cures out, but once it has it does a great job of sealing almost anything and at very high temperatures.

I use this for high heat, and food contact places. I grow micro greens in a hydroponic system and use this to seal edges for custom hydroponic NFT tables for automated watering. I also use it on high heat application in my mushroom grow facility where I cook sawdust for 24 hours at a time. Works great, really good bond, never fouls after opening if you seal it properly, and I always keep an extra tube on hand.
