Permatex The Right Stuff 90 Minute Gasket Maker is a formed-in-place gasket material designed for high-torque and high-vibration automotive applications. This elastomeric sealant is blowout-resistant and protects against leaks and seepage caused by vibration and thermal expansion, offering more reliable and longer-lasting sealing than pre-cut gaskets.
The key advantage of this gasket maker is its rapid cure time: it returns your vehicle to service in just 90 minutes, compared to 24-hour curing times of standard RTV silicones. It can be used either to build new gaskets or to dress existing gasket surfaces, offering versatile repair solutions in a single product. The formula is specified for high-torque and high-vibration applications and is formulated to meet or exceed OEM performance standards for long-term sealability and durability.
