Dynatex® Blue Medium Strength Threadlocker Gel is a medium strength anaerobic threadlocking material, which cures between engaged threads to form a unitized assembly that resists virtually all leakage, shock and vibration. The product is a single component, anaerobic gel that cures when confined in the absence of air between close fitting metal surfaces. Ideal for all ¼ inch to 1 inch diameter nut and bolt assemblies. Excellent chemical resistance with a temperature resistance range of -75°F to 300°F (-59°C to 149°C).
