Abstract
A technique for joining a larger and a smaller pipe wherein the smaller pipe has an outside diameter smaller than the inside diameter of the larger pipe. An inner and an outer gasket are used to form the joint. The inner gasket has an inclined outer surface forming a wedge shaped profile and is stretch fitted over the smaller pipe. The outer gasket has a portion of its inner surface matched to the inner gasket outer surface and is compression fitted into the inner surface of the larger pipe whereby the portion of the smaller pipe having the inner gasket is encased by the larger pipe. The smaller pipe is then pulled away from the larger pipe until the inner gasket wedges against the outer gasket forming a locked sealed joint.
