NuFlex 302 Hi-Temperature Silicone Sealant is a one-part non-slumping silicone sealant with the consistency of toothpaste. It cures when it is exposed to moisture in the air to form a tough rubbery seal. NuFlex 302 Hi-Temp was formulated to perform at temperatures ranging from –65° to 260°C (-85° to 500°F) under continuous operating conditions. During intermittent exposure, the silicone sealant will withstand temperatures as high as 316°C (600°F). 

This product is recommended for sealing and encapsulating heating elements in appliances, aerospace gasketing, moving oven belts, industrial ovens and bag filters on smoke stacks. There are also many applications for this product in automobiles, RV's, boats and in small engines such as: making and/or replacing expensive paper and cork gaskets in water pumps, timing chain/belt covers, rocker covers, heat risers, and any area where high temperatures and vibration are prevalent. NuFlex 302 Hi-Temp is oxygen sensor safe. Do not use in direct contact with fuels such as gasoline or diesel fuel.

I have what I believe is a Preway log burning fire place that was installed about 28 years ago. the interior wall looks like concrete with a brick imprint. The back wall has a crack from top to bottom that is about 1/8 inch wide. do you have a product that could be used to repair this crack? Thank You, Joe
