Ultra Black Gasket Maker 13oz Cartridge

The PERMATEX Ultra Black Gasket Maker 13oz Cartridge is a maximum oil-resistant anaerobic sealant designed for engine builders, mechanics, and automotive enthusiasts who require dependable performance under extreme conditions. This gasket maker eliminates the need for traditional cut gaskets on various engine components, making it a versatile choice for both assembly and repair tasks.

This anaerobic formula cures in the absence of air, allowing it to remain workable until the assembly is bolted together, at which point it forms a strong, oil-proof seal. The ultra black pigment not only matches engine block finishes but also enhances visibility during application, reducing the risk of misapplication. It is engineered to resist engine oil, transmission fluid, coolant, and fuel, making it suitable for wet-surface applications.

Ideal for V-block engines and various performance builds, including small-block and big-block Chevrolet, Ford, and Mopar platforms, this gasket maker is particularly useful where OEM gaskets are unavailable or custom solutions are needed. Its cartridge format allows for easy dispensing through standard caulking guns, ensuring precise application and minimal waste.
