Permatex Ultra Copper Gasket Maker 85g – High Temperature RTV Silicone Sealant
Permatex Ultra Copper Gasket Maker 85g is a professional-grade high-temperature RTV silicone gasket maker designed for automotive engines and heavy-duty equipment that operate under extreme heat. Its advanced silicone formula creates durable, flexible, leak-proof gaskets that withstand high operating temperatures, vibration, and exposure to automotive fluids.
Developed to meet and exceed OEM performance specifications, Permatex Ultra Copper delivers exceptional sealing performance for high-heat applications where ordinary gasket makers fail. The premium RTV silicone resists intermittent temperatures from -54°C to 371°C (-65°F to 700°F), making it ideal for engines, turbochargers, exhaust systems, and other critical sealing areas.
The sensor-safe, low-odor, and non-corrosive formula protects oxygen sensors and modern electronic engine management systems while providing excellent adhesion to metal surfaces. It maintains flexibility after curing, allowing the gasket to absorb vibration, thermal expansion, and engine movement without cracking or leaking.
Permatex Ultra Copper also resists engine oil, coolant, transmission fluid, and many common automotive shop fluids. The high-temperature silicone forms durable formed-in-place gaskets that eliminate the need for traditional paper, cork, or rubber gaskets in many repair applications.
Professional mechanics and automotive technicians rely on Permatex Ultra Copper Gasket Maker for dependable sealing performance in both gasoline and diesel engines where maximum heat resistance is essential.
