Male Nipples are used to extend the length of threaded conduit and connect 2 electrical boxes together with the 1/2 in Conduit Nipple. This conduit nipple can be used indoors or even outdoors due to its reliable corrosion resistance. This is the "close" (shortest length) nipple for 1/2" GRC/IMC. UL and CSA safety listings will create male-to-female connection in hazloc fittings.
