Form-A-Gasket #2 Sealant 3 Ounce

The PERMATEX Form-A-Gasket #2 Sealant 3 Ounce tube is a professional-grade choice for engine builders, mechanics, and serious automotive enthusiasts who demand reliability in critical sealing applications. This anaerobic sealant is specifically engineered to create reliable gaskets on engine blocks, transmission housings, differentials, and other precision-machined components where factory gaskets are unavailable or reusable seals are preferred.

Form-A-Gasket #2 operates on anaerobic chemistry, meaning it cures only when trapped between two metal surfaces in the absence of air, creating an exceptionally strong and flexible bond that resists oil, coolant, and fuel exposure. The medium-strength formulation provides excellent gap-filling capability for surfaces with minor imperfections while maintaining superior adhesion to aluminum, cast iron, and steel components. Its flexibility after cure prevents stress cracking under thermal cycling, a critical advantage in high-heat engine compartments where rigid gasket materials often fail.

The 3 ounce tube format delivers professional coverage for multiple applications without waste, and the controlled dispensing tip ensures precise, clean application without excess material. This sealant is ideal for those rebuilding classic engines, performing complete machine overhauls, or executing custom engine swaps, making it a versatile addition to any automotive toolkit.
