Permatex High Temp Red RTV Silicone Gasket Maker 311g – Professional High Temperature Engine Sealant
Permatex High Temp Red RTV Silicone Gasket Maker 311g is a professional-grade gasket maker trusted by automotive technicians, mechanics, and OEM manufacturers worldwide. Designed for high-temperature engine applications, this advanced RTV silicone creates reliable formed-in-place gaskets that outperform traditional paper, cork, and rubber gaskets.
Unlike conventional gaskets that may crack, shrink, or deteriorate over time, Permatex High Temp RTV Silicone remains permanently flexible while maintaining a durable seal under extreme operating conditions. Consequently, it protects critical engine components against leaks caused by vibration, pressure, and repeated thermal cycling.
Its advanced silicone formula withstands temperatures from -54°C to 343°C (-65°F to 650°F intermittent), making it suitable for both standard and heavy-duty automotive applications, including towing and high-performance engines. Furthermore, it resists motor oil, coolant, transmission fluid, shop fluids, and many automotive chemicals, ensuring long-lasting sealing performance.
In addition to replacing pre-cut gaskets, this RTV silicone also coats existing gaskets to improve sealing reliability and extend service life. Because it cures into a high-strength flexible rubber seal, it accommodates flange movement without losing sealing performance.
