OEM specified. Specially formulated to withstand the harsh gear oil environment found in differentials and transfer cases. Because gear oil has friction modifiers that break down normal RTV and cause leaking, this specialty silicone has been tested to OEM specifications to ensure complete sealing. As a gasket maker, it seeks and seals leak paths that cut gaskets cannot. It can also be used to seal cut gaskets.
For best results, clean and dry all surfaces with a residue-free solvent, such as Permatex® Brake & Parts Cleaner.
Cut nozzle to desired bead size gaskets are best formed using a 1/16″ to 1/4″ (2 to 6 mm) bead.
Apply a continuous and even bead of silicone to one surface; surround all bolt holes. Assemble parts immediately. Finger tighten bolts until material begins to squeeze out around flange. Allow to dry for one hour then retighten 1/4 to 1/2 turn.
Silicone dries in 1 hour, and fully cures in 24 hours. Allow more time in cold or very dry conditions.
Replace cap after use.
Note: Not recommended for use on head gaskets or parts in contact with gasoline. Store below 80°F (27°C).
