Product review (1 stars): Did not fit
Someone else bought this for me to replace a broken filler cap.  Though it says "Hamilton Beach" the cap did not fit tightly on the Hamilton beach urn lid.  When I tried to fully tighten it, the nut popped off the thread.  I warmed the seal with hot water to soften it some, and turned the nut, the glass cap broke, rendering the pot useless and the money wasted.
