Abstract: A gas service riser assembly and ductile pipe to plastic pipe transition connection is provided. The gas service riser assembly comprises an outer ductile pipe, a plastic pipe having open ends disposed within the outer ductile pipe and extending through one end thereof, a hollow rigid stiffener disposed within the interior of a portion of the plastic pipe within the outer ductile pipe, a gasket positioned around the exterior of the plastic pipe adjacent to the stiffener, and a crimp formed in the outer ductile pipe adjacent to the stiffener and the gasket whereby the outer ductile pipe is compressed against the gasket, plastic pipe and the stiffener to form a seal.
