Abstract
A coupling assembly for securing two conduits together includes a coupling sleeve, a compression nut, and a stop seal ring. The coupling sleeve includes an outwardly-protruding stop flange, and the stop seal ring fits over the coupling sleeve without sliding past the stop flange. The coupling sleeve enters an expanded end of a first conduit until the stop seal ring is squeezed by the stop flange and the conduit. The conduit sleeve is crimped with the first conduit, and the nut with a compression ring therein is screwed onto the conduit sleeve. A second conduit is inserted into the nut and the conduit sleeve, and tightening the nut compresses the compression ring to grip and secure the second conduit. With the stop seal ring squeezed between the stop flange and the first conduit, the coupling assembly protects against rain or other liquids from entering the conduits.
