摘要： An adapter for connecting a plastic pipe to a metal pipe. The adapter consists of a connector having a first end and a second end with an opening extending through the second end of the connector and extending a distance through the connector toward the first end of the connector forming an inner peripheral surface. The second inner peripheral surface of the connector is threaded forming a second inside diameter of the connector which is smaller than an outside diameter of the plastic pipe. The end of the plastic pipe is threaded into the opening through the first end of the connector with the threads digging into an outer peripheral surface of the plastic pipe and compressing a portion of the plastic pipe near the first end thereof for connecting the plastic pipe to the connector. The second end of the connector is adapted to be connected to one end of the metal pipe.
