Abstract
A field assembled gas riser includes an adapter having plural inner grooves that receive the outer surface of a plastic gas line as it is plastically deformed by axial insertion of a stiffener into the gas line. The gas line is terminated at a desired location, the adapter slid over the terminated end, and a stiffener manually inserted into the gas line. Continued axial advancement of the stiffener acts as a mandrel to plastically deform the gas line into the grooves and provide a secure, sealed arrangement.
