J-B Weld Ultimate Black Gasket Maker and Sealant is an RTV (Room temperature vulcanised) Silicone gasketing material, designed for use in mechanical assemblies where maximum petroleum and oil resistance is required. Upon curing, which occurs when the product is exposed to the moisture in the air, the silicone forms a tough, long lasting, waterproof gasket seal on most surfaces.
