Product Summary

J-B Weld Ultimate Grey RTV Gasket Maker Sealant in a 9.5 oz (280 mL) cartridge is engineered for high-performance mechanical and automotive assemblies where standard silicones often fail. This low-odor, sensor-safe RTV silicone is ideal for high-torque, closely spaced bolt configurations, forming a strong, flexible, waterproof seal upon exposure to air moisture. It resists oil, petroleum, and water, and won’t shrink, crack, or break down over time. Withstanding intermittent temperatures up to 500°F, it’s perfect for use on metal components in high-load environments such as valve covers, oil pans, and timing gear covers. Ultimate Grey ensures durable sealing in demanding applications where reliability matters most.

What's Included

    (1) One (1) 9.5 oz (280 mL) cartridge of J-B Weld Ultimate Grey RTV Gasket Maker & Sealant, designed for use with standard caulking guns.
