Abstract
The pipe coupler tool has a tool body with first and second ends and a tool body central axis. A first primary bore section is coaxial with the central axis and extends into the tool body from the first end. A second primary bore section is coaxial with the central axis and extends into the tool body from the second end. A secondary bore is coaxial with the central axis, extends axially from the first to the second primary sections and has a secondary bore diameter that is larger than the diameter of the first and second primary bore sections. First and second coupler end walls are provided at each end of the secondary bore section. A slot extending the length of the tool has sections with minimum widths that are slightly less than the diameter of the bore sections to which they are connected.
