The Right Stuff 1 Minute Black Gasket Maker is a premium RTV silicone sealant designed for high-performance, leak-proof gasketing. This elastomeric, "formed-in-place" material offers superior adhesion and flexibility, making it more reliable and longer-lasting than traditional pre-cut gaskets. It is blowout resistant and protects against leaks and seepage caused by vibration and thermal expansion. The product is sensor-safe, non-corrosive, and resistant to oil, coolant, and other automotive fluids. It withstands temperatures ranging from -75°F to 450°F (-59°C to 232°C). Ideal for use on valve covers, oil pans, timing covers, water pumps, and other high-flexibility, high-oil resistance applications.
