Permatex 81182 Gasket Maker, Gray, 3 oz Tube, Paste, Mild

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.
