    They fit on my unit and were cheap
  

*by S***E on Reviewed in the United States on 31 October 2023*

Be careful threading these on as your screwing metal to plastic and you can cross thread these pretty easy.  Otherwise, they fit fine and are easy to install.  I honestly couldn't tell you if they do anything in terms of preventing corrosion but they're cheap enough.Family hasn't complained of any noticeable bad flavors or smells.
