Excellent High-Temperature Gasket Maker That Seals Reliably
I used the Permatex Ultra Red 81630 on a high-heat automotive application, and it performed exactly as expected. It spreads easily, creates a strong, flexible seal, and handles high temperatures without cracking or shrinking. The curing process was straightforward, and once fully cured, it provided a leak-free seal. It's perfect for exhaust manifolds, headers, turbo components, and other high-temperature areas. The 3 oz tube is easy to use and provides enough material for several repairs. I would definitely buy it again for future automotive projects.
