    Useless, They forgot to thread one end.
  

*by B***. on Reviewed in the United States on August 30, 2020*

Forgotten step in the manufacturing process.One end was smooth bore and not threaded like the photos or the original part it was supposed to replace.  I don’t even think it’s worth rolling the dice to get a replacement.
