Permatex 81182 is a 3 oz. Gear Oil RTV Gasket Maker engineered specifically for the harsh gear oil environment inside differentials and transfer cases. Standard gear oils contain friction modifiers that break down ordinary RTV silicone and cause leaks. This specialty silicone is tested to OEM specifications to resist those additives and maintain a complete seal. Used as a gasket maker, it conforms to mating surfaces and fills leak paths that pre-cut gaskets can miss. It can also be applied over cut gaskets as a supplemental sealant. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.

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.
