I have a feeling it is some part of ventilation for the seat or something. It has a flexible "tubrine" looking wheel on one end and a fitting that makes it look like it is meant to spin on the other, with a foam ring that would seem to be for sealing purposes. And there is a "5" molded into it on one of the notches of the coupling end.
