Abstract: A seal used with crimp-type couplings to provide a fluid tight joint has a ring that surrounds a point. The ring has a multiplicity of cross sections. Each cross section may have the same shape and area at every position along the entire length of the ring. Each cross section has a centroid. The ring is divided into portions. Each portion subtends an angle measured about the point. Each portion is characterized by the distance from the point to the centroids of the cross sections within the portion. Centroids of the cross sections in a first portion are positioned at the same distance from the point. Centroids of the cross sections in another portion are positioned at respective points different from the distance associated with the first portion. By offsetting the centroids leak paths are intentionally created before the joint is crimped to prevent false indications of a crimped joint.
