Corteco HT300C High-Temperature RTV Silicone Gasket Maker 80 ml (+300°C) | Black

Premium quality Corteco HT300C High-Temperature RTV Silicone Gasket Maker, specifically formulated for professional automotive and industrial engine sealing applications. Packaged in an 80 ml tube, this heavy-duty black silicone withstands continuous operating temperatures and short-term thermal peaks up to +300°C. It cures at room temperature to form a permanently flexible, high-strength silicone rubber seal that exhibits outstanding chemical resistance against engine oils, transmission fluids, gear lubricants, anti-freeze, and combustion gases. Designed for exceptional adhesion on metal, aluminum, and cast-iron surfaces, it effectively absorbs component vibrations and thermal expansion, preventing internal leaks in oil pans, valve covers, and water pumps.
