Abstract
A self-aligning valve assembly and a valve plug therefor includes an elastomeric valve plug having an annular outer sealing portion with an annular sealing surface for sealing a drain hole valve seating of a receptacle. A central mounting portion is secured to a pair of telescoped tubes. A flexible diaphragm with a circular convoluted fold integrally connects the mounting portion and the outer sealing portion, and is capable of yielding to permit radial and/or tilting displacement of the outer sealing portion relative to the central mounting portion of the plug to accommodate limited misalignment between the valve tubes and the drain hole.
