J-B Weld 31914 Red High Temperature RTV Silicone Gasket Maker and Sealant - 10.3 oz.

ok

The exhaust pipe broke of at the Honda engine, on my pull behind vacuum trailer, that I use to suck up cut grass or leaves when I pull it behind my riding lawn mower. I wired the 10 inch exhaust pipe so that it would not move and then I put a bead of this high heat silicone maker to see if it would stop the loud noise coming from the Honda engine. WOW ! I started using the engine the next day and the engine sounds like a new one. Love this red high heat silicone.

My feedback is really positive because this product is so easy to use. The bonding is strong and holds well, which has saved me countless times. Another feature that stands out is the high temperature resistance, it just works wonderfully even in high heat situations. All in all, this is a solid, dependable product that does the job as promised.

Very impressed with product. Perfectly sealed my two valve rocker covers on my big V8 turbo instead of using gaskets. I made a sample dab the size of a bottle top and half inch high onto cardboard and let it set overnight and I was amazed how well it can compress without destruction and still return to its original dab size. Will definitely use this gasket maker again on my future engine repairs.

I sealed my offset smoker with this product.Follow the instructions and voila no leaksGreat high temperature silicone.

I used this in a DIY exhaust system repair, the flex connection on a Muranmo developed a hole resulting in a load exhaust, the design of this system does not allow for a replacement flex pipe replacement.After verifying that the temp does not exceed 600 degrees I used this product to seal the flex connector, I used a piece of tin to wrap the repair and used hose clamps to secure it in place This saved me around 500$. The high temp silicone has worked perfectly
