Customer Questions & Answers

IS this Food Safe, I see it is USDA Approved, Approved for what?

I want to use the Red silicone to seal a Brand new Food Smoker. I see that your ad says "USDA Approved" Approved for what? Use around food I assume but to be sure I am asking. Thank You
Asked by: FoodSmoker
6/30/16- I too need Food Grade High Temp sealant. I did call the tech @ 800-231-3345, he said "No", this sealant in not Food Grade. He did not care what kind of smoker grill i had. So I will not be buying this product for my smoker. I hope this helps!

Hi-Temp Red Silicone Caulk is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from So Far, So Good Needed to caulk around the flue pipe of a pellet stove. Couldn't find this product last year when we installed initially, and the caulk on the outside of the house had become brittle after only a few months. This seems to be a much better product for the purpose.

Rated 5 out of 5 by from Product did the job! The Hi-Temp Silicone caulk was exactly what I was looking for. It filled the gap between the studs and chimney. The caulk was easy to work with and will use again.

Rated 5 out of 5 by from REAL BANG FOR YOUR BUCK This is the second tube of this hi-temp caulk I have reciently ordered. I didn't really need this one but realized this is the same caulk I purchase in smaller tubes for automotive repair at the auto parts store. So now I have 10 times the reserve caulk at about 1/10 of the cost.

Rated 5 out of 5 by from Stuff worked great I used this hi temp RTV silicone caulk to seal an inducer transition box on a gas fired boiler that was whistling like a train engine whenever it operated. Now it's working great and I can't even hear it running. I won't really know how good the product was for another 10 years, but it sure solved the problem!
