Technical Examples

A pipe coupling for joining a first pipe to pipes of varying diameters includes first and second hollow fittings which are secured together in end-to-end relationship by a crimping process to rigidly hold the fitting members together to form a continuous fluid passageway. The first fitting member is comprised of metal, and a second fitting member is comprised of plastic material. The second fitting member has a pair of well openings with the outer well adjacent one end thereof being of a greater diameter than the inner well. The outer well is adapted to receive the end of a hollow plastic pipe of greater diameter, e.g., Â¾?. The second well is available alternatively to receive the end of a plastic pipe of reduced diameter, e.g., Â½?.
