What Customers Are Saying
This high-temperature sealant is generally effective for sealing gaps and joints in stoves, furnaces, and other high-heat applications. Many customers report successfully using it to seal stove pipes and furnace gaskets, with the sealant holding up well to high temperatures. However, some found it did not perform as well at the claimed 600°F maximum temperature, with the sealant crumbling or falling off when used on wood stoves. Overall, the product appears to work well for most common stove and furnace applications, though users should be aware of potential limitations regarding maximum temperature.

Works Well
Would RecommendPurchased this to seal a smoker. Tube tip has guidelines to help with size of bead. Can be messy if you are not careful, but its to be expected with silicone. Stood up to 400 degrees with no burning, shrinking, or foul odor.
