Abstract:
1. A swivel coupling for nonmetallic electrical conduit, the coupling comprising a first tubular section and a second tubular section, each tubular section having a connecting flange at one end, each connecting flange having a substantially planar face, the faces of the connecting flanges extending parallel to a common reference plane, a coupling nut having a minimum internal diameter securing the connecting flanges together, the tubular sections being rotatable relative to one another when the coupling nut has not been tightened and being fixed relative to one another when the coupling nut is tightened, an end of the first section opposite the connecting flange including a nipple having a threaded portion and an end of the second section opposite the flange including a conduit fitting, the first section including a stop flange at an inner end of the threaded portion, a stop nut positioned on the threaded portion in abutment against the stop flange, a groove formed in the stop nut, and the stop flange being seated in the groove, the stop flange having a diameter less than the minimum internal diameter of the coupling nut, the stop nut having a maximum transverse dimension greater than the minimum internal diameter of the coupling nut, whereby the swivel coupling may be assembled by passing the coupling nut over the nipple and over the stop flange to engage the connecting flanges prior to positioning the stop nut on the threaded portion of the nipple.
