Product ReviewsPermatex 81878 Silicone Gasket Maker

Excellent exhaust sealant

The gasket sealant is very good. I have used it to seal the problematic exhaust joints on my Ducati motorcycle. I had tried a few times before to stop the exhaust blowing before using this product, which has instantly cured the problem. Just make sure you use plenty of it, don't be mean, and it will do the job.Read full review...

Mx5 exhaust

Had a problem with leaking flange joints on a mx5. This stuff cured it. Better application than some of the fire putty products. Word of advice, follow the instructions and let the product "cure" for 24 hours before subjecting to use.👍Read full review...

Quality Product

It does what you want it to do. Easy to apply and forms a perfect seal if the instructions are followed. Used when connecting a new exhaust and it's worked perfectly. Lots spare too.

Best product for exhaust leaks and as a gasket around flanges

This is the best product by far to address exhaust leaks - especially as in my case, I used it for a high performance, high temperature car. It is truly perfect!
