Hi Tack Gasket Sealant

Permatex Hi Tack Gasket Sealant is a specialized anaerobic adhesive designed for professional mechanics and automotive enthusiasts who require reliable, long-lasting gasket sealing without traditional cork or rubber gaskets. This product is particularly useful in high-vibration environments, such as modified engines and heavy-duty applications, where conventional gaskets may fail or deteriorate over time.

Hi Tack Gasket Sealant cures anaerobically, meaning it hardens only in the absence of oxygen when sandwiched between two mating surfaces. This curing mechanism results in a flexible, oil-resistant seal that withstands extreme temperature variations, vibration stress, and chemical exposure from coolants and oils. Its formulation resists washout even under severe pressure cycling, making it ideal for applications like engine blocks, transmission housings, and oil pans.

Mechanics and engine builders benefit most from Hi Tack when working with custom or non-standard gasket surfaces, ensuring leak-free operation in freshly honed blocks. The product's high tack characteristic helps hold components in alignment during assembly, preventing misalignment before the curing process is complete, which is crucial for precision machine work.
