Abstract
The bar seal for use in a rotary mechanism and which is disposed for sliding movement in a groove and to sealingly engage a surface, has an elongated base structure of high wear resistance characteristic and a body portion of a material having a low coefficient of friction connected to the base structure to form a unitary assembly. The body portion is dimensioned to extend a substantial part of the length of the base structure and of a width to form opposite planar surfaces for contacting the walls of the groove.
