With the Loctite si 5699 GY, you quickly create a tough, flexible flange seal. This grey silicone sealant in a convenient 80 ml tube is designed for sealing rigid flanges on components such as transmissions, oil pans, valve covers, and cast housings. Thanks to its superior resistance to automotive oils and water-glycol mixtures, you reliably prevent leaks. It adheres firmly to machined or cast metal surfaces as well as plastics, easily withstanding joint movement, vibrations, and thermal expansion. Because the silicone becomes tack-free in just 10 minutes and cures with ambient moisture, you can speed up component assembly and finish maintenance jobs faster.
