Abstract:
A swivel coupling for electrical conduit is formed of a pair of arcuate tubular sections joined together at a pair of connecting flanges. A liquid tight seal is provided by an O-ring which seats in registered annular grooves in the face of each flange. A coupling nut tightens the flanges against one another. Formed at the end of one of the sections is a junction box fitting including a threaded nipple which is inserted through an opening of the junction box until a stop nut, positioned on the nipple, engages the box. A tightening nut is engaged over the nipple from the interior of the junction box to secure the swivel coupling to the box. The end of the other tubular section includes a conduit fitting for securing a length of electrical conduit. Because the stop nut is installed after the coupling nut has been advanced past the nipple, a reduced diameter coupling nut may be employed.
