Product review (5 stars): A perfect OEM replacement part.
This OEM part is a perfect match to the original!  Whirlpool has improved the original all plastic part so that the threaded portion of this one is metal, with only the outside cap being plastic.  It will not be susceptible to breakage.

A great OEM part, a great price, and a great seller!  It arrived one day early!  I highly recommend the part and the seller!
