Claim Text:
1. A coupling for a waste disposal system for a recreational vehicle, the coupling comprising: (a) a first coupling portion having an inner end and an outer end, the outer end being configured for a non-rotatable connection to a first waste disposal component; (b) a second coupling portion having an inner end and an outer end, the outer end being configured for a non-rotatable connection to a second waste disposal component; and (c) the inner end of the first coupling portion being snap fit to the inner end of the second coupling portion such that the first coupling portion and the second coupling portion rotate with respect to each other when a connection is created between the first and second waste disposal components, wherein the first coupling portion comprises a radially inwardly extending lip formed at the inner end thereof; and the second coupling portion comprises a circumferential groove radially extending around the outer surface of the inner end thereof, the snap fit provided by engaging the lip of the first coupling portion with the groove of the second coupling portion; wherein a separate sealing member is not used between the first coupling portion and the second coupling portion, and leakage or seepage of waste material between the first coupling portion and the second coupling portion is insubstantial under normal conditions without the use of the separate sealing member; and a lubricant that is applied between the lip and the groove to minimize friction during rotation of the first coupling portion relative to the second coupling portion.
