A sealing element, formed of a substantially non-extrudable material, is configured with a taper at one edge or surface thereof. The element is set in a recess which obtains between interengaged components, with the tapered end exposed, externally. The tapered end is flat, and fairingly bridges across the recess to obviate any crevasses or notches, or voids in which product fluid can repose and create bacteria.
