Automatic Transmission Torque Converter Seal by National®. Front. Width: 0.33". Inside Diameter: 1.748". Outside Diameter: 2.627". Housing Bore: 2.619". Don’t just repair a leak, prevent future problems with a National Oil Seal. This part is manufactured using exclusive National Dynamic Edge technology that generates a dynamic pumping action to keep harmful contaminants such as dirt, moisture, etc. out of the seal and other wheel-end components.
Engineered for performance, National oil seals deliver superior protection and long service life thanks to premium material construction and a patent-pending National Dynamic Edge technology used in their manufacture. This innovation aggressively deflects dirt, liquid, and other contaminants that can lead to premature seal and bearing damage and diminished wheel-end performance. The National Dynamic Edge design consists of an integral sinusoidal wave that produces a dynamic pumping action to move contaminants away from the seal. This innovation ensures maximum protection from environmental contaminants under even the most adverse conditions. This part is engineered to meet OE specs to perfectly fit your vehicle.
