[High-Temperature Resistant]: This RTV silicone sealant withstands extreme temperatures from -54℃ to 340℃ without losing flexibility. It cures at room temperature into a firm rubber-like gasket that stays pliable across numerous heat cycles. Unlike hard adhesives, it absorbs engine vibrations and thermal expansion, preventing cracks and bond failure. This reliable sealant works well for valve covers, thermostat housings, exhaust manifolds, and turbocharger flanges
[Oil Resistant]: This sealant offers strong resistance to engine oil, transmission fluid, coolant, and brake fluid, preventing leaks that can damage components. It forms a tight, impermeable barrier that blocks fluid seepage along flange and gasket surfaces. Even under high pressure and continuous liquid exposure, the cured material remains stable without swelling, softening, or degrading. This reliable seal protects oil pans, timing covers, differential housings, and water pumps from stubborn leaks. The formula is specially developed for automotive powertrain applications, giving a proven solution to stop fluid migration and preserve engine integrity
