Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker 81878 85gm

Product Description

Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker  is a premium, single-component, room-temperature vulcanizing (RTV) gasketing paste designed for high-performance mechanical assemblies. Tested and verified to exceed OEM specifications, this advanced copper-colored formula relies on ambient moisture to cure into a tough, permanently flexible silicone rubber seal.
It offers the ultimate protection against structural thermal cycling, extreme heat up to 700F (371C), and continuous vibration. It is specifically engineered to resist common workshop and automotive fluids while providing up to 3 times greater oil resistance than conventional silicones and 8 times higher flexibility than pre-cut stamped gaskets. The sensor-safe, low-odor, and non-corrosive composition ensures zero interference with electrical and automated engine control units.
