COUPLING NUT
A coupling nut ( 108 ) for joining a pair of conduits ( 104, 106 ) is provided. The coupling nut includes a first end ( 124 ) and a second end ( 126 ). An opening extends between the first end and the second end. The opening has an interior surface. A first coupling nut thread ( 114 ) extends along the interior surface at the first end and is constructed and arranged to receive a first conduit thread ( 110 ) having a first length (L 1 ). A second coupling nut thread ( 116 ) extends along the interior surface at the second end and is constructed and arranged to receive a second conduit thread ( 112 ) having a second length (L 2 ). A non-threaded central portion ( 118 ) extends between the first coupling nut thread and the second coupling nut thread. The non-threaded central portion ( 118 ) has a third length (L 5 ). The third length (L 5 ) of the non-threaded central portion is less than the sum of the first length (L 1 ) of the first conduit thread and the second length (L 2 ) of the second conduit thread.
