Abstract
A coupling can include a coupling body having an axis, an axial length, an axial center, axial ends and an inner surface comprising an inner diameter that is substantially constant over an entirety of the axial length. A single shoulder can protrude radially inward relative to the axis from the inner surface, such that the inner surface has no other shoulders. In a version, the single shoulder is not axially aligned with the axial center of the coupling body.
