ABSTRACT:
A gasket is provided for joining lengths of pipe having dissimilar end faces which are of approximately equal diameters and which are substantially normal to the longitudinal axis of the pipes. The end faces each include a circular recess which are of differing diameters. The gasket has a first side which has a surface contour which is a mirror image of one of the faces and the opposite side has a surface contour which is a mirror image of the other end face. The outer periphery of said gasket is of a substantially lesser thickness than its inner marginal portion so that compression during use of the thicker inner marginal portion is minimized.
