Product Summary

J-B Weld Ultimate Grey RTV Gasket Maker Sealant is specially engineered for high-stress mechanical assemblies where typical silicone sealants may fail. This 3 oz tube delivers a low-odor, room temperature vulcanizing (RTV) silicone formula designed to withstand high torque loads, closely spaced bolt patterns, and exposure to oil, water, and high temperatures. Ideal for use on metal and in automotive applications, it forms a strong, flexible, waterproof seal that won’t shrink, crack, or degrade over time.
