A method for tightening a pipe coupler includes the steps of attaching a first end of the pipe coupler to a pipe, attaching an adapter to a second end of the pipe coupler, attaching an air gun to the adapter, tightening the pipe coupler by operating the air gun, and, after the tightening, removing the adapter from the pipe coupler. Threaded portions of the pipe and the pipe coupler are tapered, while the threaded portion of the adapter is not tapered. In an alternate embodiment, the adapter comprises a baffle and a ball on an inner surface.
