ABSTRACT:
An apparatus and associated method is for forming an end of a piece of gas conduit and attaching it to a second piece of conduit. The apparatus is provided for smoothing the end of a corrugated conduit and expanding it to a predetermined diameter. An associated connector is then applied to the smoothed end of the corrugated conduit and the conduit and the connector are then connected to the second piece of conduit. An associated method provides steps for achieving such a connection.
