COUPLING ASSEMBLY FOR CONNECTING A DRAIN TO A DRAIN PIPE
The present invention relates generally to a kit for coupling a first pipe to a second pipe. The kit includes an elastomeric coupling sleeve provided with top and bottom ends sized to snugly fit within the respective first and second pipes. The coupling sleeve includes top, intermediate and bottom portions and an inner surface that defines a passageway. A first passageway portion extends between the top and intermediate portions and a second passageway portion extends between the intermediate and bottom portions. The first passageway portion tapers toward the intermediate portion and has threading formed along the inner surface. The second passageway portion tapers toward the intermediate portion and has threading formed along the inner surface. The kit also includes top and bottom rigid expansion rings that have threading formed along their outer surfaces configured for engagement with the threading formed along the inner surface of the first and second passageway portions, respectively. When operatively connecting the coupling sleeve to the first and second pipes, each expansion ring is threadingly engageable with the associated portion of the coupling sleeve so as to urge the coupling sleeve in the region of the expansion ring to bulge outwardly and seal the coupling sleeve against the respective first and second pipe.
