The Right Stuff Gasket Maker 5oz Cartridge

The Right Stuff Gasket Maker 5oz Cartridge by Permatex is the go-to sealant for engine builders, mechanics, and automotive enthusiasts who demand reliable, long-lasting gasket sealing without the mess of traditional loose sealers. This premium anaerobic gasket compound is engineered for applications where you need superior oil resistance and thermal stability, making it ideal for engine gaskets, transmission pans, differentials, and other critical engine compartment seals. Whether you're rebuilding a vintage classic, freshening a performance engine, or executing routine maintenance, this cartridge format delivers precision application and consistent results.

This anaerobic formula cures in the absence of air when confined between two metal surfaces, creating a flexible, durable seal that resists petroleum products, coolant, and temperature fluctuations typical of engine environments. The 5oz cartridge format fits standard caulking guns, allowing controlled, bead-accurate placement that minimizes waste and ensures even coverage on irregular surfaces—critical when sealing cast iron or aluminum engine blocks where surface flatness varies. The material achieves full cure strength in 24 hours at room temperature, though partial handling strength develops within hours, reducing downtime on repair jobs and engine assembly work.

Professional technicians and serious hobbyists rely on The Right Stuff Gasket Maker for both OEM gasket replacement and custom applications where traditional cork, paper, or composite gaskets may not perform under elevated temperatures or aggressive fluids. The compact cartridge format (2.55 x 1.9 x 5.85 inches, 0.52 lbs) fits easily in any toolbox and eliminates the shelf-life concerns of tube sealers. Compatible with all common engine materials including cast iron, aluminum, steel, and composite gasket surfaces, this sealant works across domestic and import platforms—from muscle cars to modern turbocharged engines.
