    Black RTV Silicone Gasket Maker, 300 mL Cartridge

    Part #: DYN-49290

    Dynatex 143393 is a sensor-safe, one-component black RTV silicone gasket maker that extrudes as a non-slumping paste and cures at room temperature to a tough, flexible rubber—ideal for forming in-place gaskets on engines, drive-train equipment, differentials, and transfer cases. It resists oil, water, antifreeze, and transmission fluid; withstands gear-oil environments; and maintains performance across extreme temperatures, making instant, leak-proof gaskets that meet OEM demands.
