ABSTRACT:
A seal assembly capable of sealing a rotatable shaft protruding from a fluid-containing chamber in an internal combustion engines and the like. The seal characteristics of the seal assembly are largely attributed to surface interface between the seal cap and the main body of the seal assembly. More particularly, the seal cap includes a pair of legs each having fractured ends which are in end-to-end engagement with corresponding legs of the main body also having fractured ends. By mating corresponding fractured ends of respective legs of the seal cap and the main body, an improved seal is provided. A method by which such an improved seal assembly can be manufactured is also disclosed.
